A good password manager makes it easier to create and use a different strong password for every account. The trade-off is that more of your digital life depends on one manager account, so its encryption, multi-factor authentication (MFA), and recovery design matter. Compare services against the six checks below, then rule out any that fail a requirement you cannot compromise on.
1. How does the manager protect your vault?
Find out how vault data is encrypted, where encryption happens, which fields are protected, and who can access the keys needed to decrypt it. For a cloud-sync service, ask whether the provider can read your vault contents, and look for technical documentation that explains the answer.
Terms such as “zero knowledge” and “end-to-end encryption” are useful starting points, not proof by themselves. Check them against the provider’s architecture documentation and independent assessment evidence. Encryption protects stored data; it does not make a compromised device, an unlocked session, or a stolen master secret harmless.

A password manager can help you avoid reusing passwords by generating and storing unique ones. That makes the manager’s own account and master secret especially important to protect. NIST’s official password guidance says, “For accounts that require passwords, NIST experts highly recommend that you use a password manager.” Its separate digital identity FAQ clarifies that SP 800-63B does not explicitly recommend password managers; it recommends allowing users to paste passwords. The guidance also advises a long master passphrase, unique generated passwords, MFA where available, and caution with recovery mechanisms. See NIST’s digital identity FAQ and NIST’s password guidance.

- TRUSTED PASSKEY TECHNOLOGY: Uses the latest passkey standards (FIDO2/WebAuthn & FIDO U2F) but does not support One-Time Passwords. For complex needs, check out the YubiKey 5 Series.
- BUILT TO LAST: Made from tough, waterproof, and crush-resistant materials. Manufactured in Sweden and programmed in the USA with the highest security standards.
2. What independent security evidence is available?
Look for named third-party assessments, their dates and scope, and public reports where available. Also check whether the provider has a vulnerability disclosure process, explains how to report issues, and communicates how it handles incidents and patches.
An assessment is evidence about a particular scope at a particular time, not proof that a service has no vulnerabilities. For example, 1Password’s support page says Independent Security Evaluators (ISE) performed a penetration test and code review in April and June 2020. That is vendor-published information about assessments conducted in 2020, not evidence of a recent audit. Read the vendor’s security-assessments page.
Give more weight to evidence you can evaluate than to broad security labels. A useful comparison records the assessor, date, what was examined, and whether the report is public; it also notes the provider’s disclosure and patch practices.

3. Which MFA and recovery options fit your risk?
For a cloud-sync manager, enable MFA if the service supports it. Compare the factors it accepts and what happens if you lose access to one. A hardware security key can be an optional second factor, but only if the manager supports the relevant standard and your account configuration; some MFA methods require purchasing a token.

- Requires 3 "AAA" batteries (included)
- Unit auto-locks for 30 minutes after 5 consecutive incorrect PINs
Recovery is a security and usability trade-off. Check whether an emergency contact or team administrator can help restore access, what identity checks are required, and whether recovery can unlock encrypted vault contents. A recovery route can reduce the chance of being permanently locked out, but it also creates another way to regain access. Tighter recovery controls may mean losing the vault if the master secret is lost.
NIST’s FAQ specifically advises caution about recovery mechanisms that could compromise a vault. Decide before choosing whether you value a simpler path back into the account or stricter limits on who can restore access. NIST’s FAQ discusses password-manager recovery.
4. Will it work across your devices and daily workflows?
Check support for the operating systems, browsers, phones, tablets, and important apps you actually use. Then try saving and filling credentials in the real workflows that matter—for example, a browser login, a mobile app, and a shared household account. Platform support on a feature list does not guarantee that autofill behaves well in every app or site.
Usability affects whether a manager gets used consistently. The UK National Cyber Security Centre (NCSC) warns: “If users do not find the password manager easy to use and useful, they won’t use it, workarounds will persist, and its benefit and costs will go to waste.” Missing support can push people toward insecure workarounds, so treat compatibility as a practical requirement, not a bonus. Read the NCSC’s password-manager guidance.
Cloud sync can make vault data available across devices. On-device storage can limit remote exposure, but may be a poor fit if you need credentials on several devices. Choose based on where you need reliable access and how the service handles synchronization.
5. Can you leave without exposing your passwords?
Before committing, check which import and export formats the service supports and whether it can migrate data from your current manager. A workable exit route gives you more choice later, but exported credentials may be in plain text and unprotected.
- Check the export format and migration instructions before you need them.
- If you export, save the file only where you can protect it; do not leave it in Downloads or an unprotected cloud folder.
- Import the data into the destination manager, confirm the credentials transferred, then securely remove the export file and any copies.
NCSC also warns that exported passwords may be stored without protection. Treat an export as a sensitive credential file, not an ordinary backup. NCSC’s guidance covers password-manager exports.

Common questions
Is a free password manager good enough?
It can be, if its current free plan supports the devices, sync, MFA, recovery, and sharing you need and its security evidence is acceptable to you. Check the plan’s limits and renewal terms; the word “free” alone does not establish whether it fits.
What is NIST’s position on password managers?
NIST’s password guidance highly recommends using a password manager for accounts that require passwords. Its digital identity FAQ adds that SP 800-63B does not explicitly recommend managers, while advising that systems allow password pasting. These are distinct statements, not a contradiction: the FAQ describes what the standard says, while NIST’s separate guidance expresses its recommendation.
How hard is it to switch password managers?
Difficulty depends on whether the destination can import your current manager’s export format and whether the credentials transfer correctly. Check compatibility first, protect any exported file because it may be plain text, verify the import, and securely remove the file afterward.
