Are password managers safe in 2026?
Password managers aim to protect sensitive information, including login credentials, payment details, and secure notes. Without one, it can be easier to fall into risky password habits, such as reusing credentials or relying on weak, predictable combinations.
A 2025 FIDO Alliance survey found that 36% of respondents had experienced at least one account compromise because of weak or stolen passwords. A trusted password manager can reduce this risk by generating and storing strong, unique passwords for each account.
However, not all password managers offer the same level of protection. Strong encryption, zero-knowledge architecture, multi-factor authentication, and a solid security track record are all important when choosing a provider.
In this article, you'll find everything you need to know about password manager security – how password managers work, the methods they use to protect your data, the potential risks involved, and whether using one is a smart choice. Let’s dive in.
How do password managers secure your passwords?
There are multiple ways that password managers secure your passwords – starting with a secure encryption process that uses a specific cipher to protect the transfer of data online. AES-256 is one of the most widely used encryption standards, while XChaCha20 is another modern encryption algorithm used by password managers such as NordPass. Both are designed to provide strong protection for encrypted data.
The zero-knowledge architecture used by the top password managers ensures that passwords are encrypted before they leave your device. When they’re on a server, even the provider has no way to decipher them. Some password managers will remind you to change passwords regularly and evaluate their strength. Others will also scan the dark web to check if any of your logins got leaked online.
The master password is typically the main password you need to remember to unlock your vault. You should make it long and unique, and protect your account with an additional authentication method where available. Adding multi-factor authentication (MFA) provides another layer of protection by requiring two or more authentication factors when you sign in. Biometric authentication, such as a fingerprint or facial recognition, can also make accessing your vault more convenient while adding another layer of protection.
Types of password managers
Those familiar with password managers probably know about the three main types: browser-based, cloud-based, and desktop-based. Each comes with its own set of pros and cons, including those related to security. Let's discuss all types one by one and figure out which one is the most secure.
Browser-based password managers
Browser-based password managers are popular because they’re free and very convenient to use – you don’t need to use a separate app to save and autofill your passwords. However, they’re not considered the safest.
| Security level | Medium |
| Examples | Built-in browser password managers (Chrome, Firefox, Safari) |
While encryption and two-factor authentication make browser-based password managers pretty safe, there are quite a few security-related concerns.
For starters, browser-based password managers work on one particular browser. If, for example, you decide to move from Safari to Chrome or Firefox, you might have trouble exporting and importing data. Furthermore, there's no way you could synchronize your vault on different browsers. All this often leads to storing your passwords in a location that’s not secure.
Second, not all browser-based password managers have a password generator. Without one, you will have to create passwords manually, and most users opt for simpler and, thus, more vulnerable ones when they’re presented with the option.
Lastly, features such as weak-password checks and breach monitoring vary between browser-based password managers. Therefore, if you want to know if your logins aren’t available on the dark web, you might have to use a separate tool.
Cloud-based password managers
Cloud-based password managers are safer than browser-based password managers, as they have more features that enhance security.
| Security level | High |
| Examples | NordPass, 1Password, RoboForm |
To begin with, most cloud-based password managers provide a backup for your vault. This means that if something happens to the server, you can recover a recent version of your database.
Furthermore, cloud-based password managers, like NordPass, allow you to store not only passwords but also secure notes and credit card details. This enables you to protect all sensitive information, not just logins.
Additionally, cloud-based password managers can detect reused and weak passwords, generate strong ones, and check if your logins have been leaked. They also let you share your vault entries easily, even with those who don't use the same service.
Finally, cloud-based password managers work on multiple browsers and operating systems. It means that you don't have to think about how to copy and paste something from your database securely.
On the downside, cloud-based password managers are potentially vulnerable to cyberattacks – no one can give you a 100% guarantee that your vault will be secure. Of course, the risk decreases significantly when you employ reliable managers.
Furthermore, keep in mind that not all password managers work offline, so if you don’t want to be locked out when the internet connection is unstable or unavailable, pick a solution that supports you both online and offline.
Desktop-based password managers
When it comes to desktop-based browsers, they can be the safest; however, that completely depends on the user.
| Security level | Highest |
| Examples | 1Password, Bitwarden, KeePass, Dashlane |
All information you store on a desktop-based password manager is, essentially, stored on your device. That means that no third party has any link to that information. This eliminates the risk of exposing your data during a data breach that could potentially affect the password manager provider. However, there are a few downsides that you should consider.
For starters, you are responsible for regular backups. If your device breaks down irreparably, your vault containing all your passwords may be gone. Since all data is stored on one device, you cannot sync it with other devices and, thus, recover it easily.
Furthermore, you should consider the possibility that someone could access your physical device without your permission and gain access to the password manager vault. To combat this, you want to make sure that you have a strong lock on your computer as well as a strong master password for your password manager.
What if your password manager gets hacked?
In most cases, getting hacked won't result in all your passwords falling into the wrong hands. However, even the most secure password manager may have a serious vulnerability that everyone overlooked.
Let's start with the fact that your passwords are encrypted locally. Password managers cannot decipher your data because they implement a zero-knowledge policy. So, if an attacker obtains an encrypted copy of your vault, they should not be able to read its contents without the necessary decryption key.
There's a slim chance the attacker could break into your physical device by stealing it, using malware, or logging keystrokes. Even then, accessing the vault may require the attacker to obtain your master password or bypass other authentication and device protections. If you use biometric data, such as fingerprint or face ID, the chance of a successful attack becomes extremely low.
If the attacker installs malware on your device, your best move is to reinstall the OS and change all passwords in your vault. Make sure to turn on 2FA or MFA, which require additional factors to authenticate a login. This way, you will notice when an unusual request comes to the authenticator app.
What are the main risks of using a password manager?
Password managers are meant to help you strengthen your digital security. However, you should remember that certain risks exist. Even though the chances of facing security problems are very low if you apply password management best practices, they shouldn’t be ignored. Here are the main risks I’m always cautious about:
- Device vulnerabilities. You may be able to sync your password manager account across multiple devices, including your mobile phone, tablet, or stationary computer. If any of them are not protected appropriately, you run the risk of facing malware. Remember that sensitive information, such as passwords or credit card details, is the most valuable to cybercriminals, so you must protect your devices accordingly. I always recommend using reliable antivirus protection.
- Data breaches. You should only trust a reliable password manager to store all of your passcodes in one place. If the provider experiences a data breach, even if your master password is strong, you could end up facing security issues. That’s why you want to choose a password manager that implements strong security practices and, ideally, hasn't experienced data breaches in the past.
- Faulty vault backups. If your password manager’s server breaks down, your only hope is that it has a backup copy. This risk increases multi-fold if you decide to keep your vault offline on one of your devices. Naturally, keeping your own backup on an unprotected disk drive or poorly protected cloud service won't help either. Fortunately, there are providers – like NordPass and 1Password – that keep backup copies for you in case of a server breakdown.
- Unreliable password managers. Keep in mind that not all password managers are equal. Top providers have the necessary security measures and features in place. However, less reliable password managers may be more prone to successful hacking attacks. Unfortunately, you have to be particularly careful about free password managers. While not all of them are unreliable – especially those that offer paid versions alongside – some may simply not have the resources to guarantee optimal security.
What are the main benefits of using a password manager?
While there are some risks to using password managers, the benefits greatly outweigh them. Here are the main advantages I found to using a reliable password manager:
- Enhanced security. If you use a trustworthy password manager that employs reliable encryption, you can enjoy enhanced protection of all your stored items, including passwords, payment card numbers, social security numbers, identification data, birth dates, or door codes. A strong master password and MFA can significantly reduce the risk of unauthorized access to your vault. You certainly cannot achieve that level of security with post-it notes, note apps, or spreadsheet documents.
- Improved password habits. When you don’t have to think about remembering complex passwords, you can easily apply password best practices. You no longer need to reuse passwords, use memorable and, thus, easily guessable combinations, or store them in unsafe locations. Long, unique, and randomly generated passwords are generally harder to guess and can provide stronger protection against password attacks.
- Convenience. Yes, convenience is a huge benefit when it comes to passwords. If you sync your accounts across different devices, you can always access them, no matter where you are. Again, the fact that you don’t need to remember your passwords provides you with an opportunity to keep all of that data extra safe. Plus, when it comes to sharing passwords, many managers make the process quick, easy, and safe.
Password manager hacks
The list of notable password managers that have been compromised is, fortunately, quite short. Otherwise, they wouldn't have the reputation they have today. Note that the list below also includes reported vulnerabilities that didn't result in any damage:
- In 2022, LastPass suffered two related security incidents. Attackers first accessed parts of its development environment and later compromised an employee's personal computer, which allowed them to access a cloud-based backup containing customer information and encrypted password vaults. The UK Information Commissioner's Office later found that up to 1.6 million UK users were affected and fined LastPass UK £1.2 million in December 2025. There is no evidence that the attackers were able to decrypt customers' passwords.
- In October 2023, 1Password reported a security incident involving its Okta environment. A threat actor accessed an internal system using a compromised Okta administrator account. 1Password said that its customer data and systems were not compromised, and there was no evidence that user vaults were accessed.
- In 2025, security researchers disclosed vulnerabilities affecting several password manager browser extensions, including 1Password, Bitwarden, LastPass, and others. The research demonstrated clickjacking techniques that could potentially trick users into exposing information through autofill. The affected providers were notified and worked on fixes.
- In February 2026, researchers from ETH Zurich and the Università della Svizzera italiana identified 27 vulnerabilities across four major password managers: 12 affecting Bitwarden, seven affecting LastPass, six affecting Dashlane, and two affecting 1Password. Some of the demonstrated attacks could allow a malicious server to manipulate or access vault data under specific conditions. The researchers disclosed the findings to the affected companies, and the providers addressed the reported issues. Importantly, there was no evidence that these vulnerabilities had been exploited in the wild.
- In April 2026, a malicious version of Bitwarden's command-line interface package was published through the npm ecosystem as part of a supply-chain attack. The compromised package was available for roughly 90 minutes and targeted developer credentials stored in CI/CD environments. This was a supply-chain incident affecting the CLI package, not a breach of Bitwarden's password vaults or customer accounts.
Conclusion: Are password managers safe?
Password managers are safe if you choose a reliable provider and implement password management best practices. If you use something like password123 as your master password to unlock your entire vault, it could easily be guessed and breached even if you use a reliable manager, especially if you don’t add 2FA or MFA for added security.
Of course, even if your master password is strong and you take all the precautions to be safe, no one can guarantee full security. In theory, cloud-based password managers, for example, can suffer breaches; thus, it’s crucial to employ providers with a proven track record of evading security incidents and taking users’ security seriously.
Don’t forget that all types of password managers can also be affected by malware inside your devices. Therefore, if you have a password manager, I advise implementing strong antivirus protection, too. Also, don’t forget to stay vigilant about phishing attacks that could be used to gain access to your vault.
