How to Choose a Password Manager

Why you need one

No one can remember dozens of long, unique, random passwords for every service they use. In practice, that leads to reusing a handful of passwords everywhere — the single most common cause of account compromise. A password manager solves this at the root: it generates and securely stores a strong, unique password for every site, and fills it in automatically when you need it. The only thing you need to remember is one master password.

What to look for

1. End-to-end encryption Confirm that your stored passwords are encrypted on your own device before ever being sent to the manager’s servers, and that even the provider itself can’t see your actual passwords (a “zero-knowledge” architecture).

2. Cross-device syncing How smoothly it syncs across every device and browser you actually use — desktop, phone, tablet — has a big impact on whether you’ll actually stick with it.

3. Browser extension and autofill quality How reliably it fills in your credentials on login pages matters a lot for day-to-day usability.

4. Emergency access / inheritance Check whether you can designate a trusted person to gain access if you forget your master password or something unexpected happens to you.

5. A transparent security track record Trustworthy providers undergo regular independent security audits and publish the results. It’s also worth checking whether they’ve had past incidents, and how they responded.

Starting for free

Your browser or OS’s built-in password manager is far better than reusing passwords manually. But if you regularly switch devices or browsers, need to share credentials with family, or want finer-grained security controls, a dedicated password manager is worth the move.

Your master password deserves extra care

Once you’re using a password manager, it remembers everything else for you — except the one master password, which you’ll always need to recall yourself. Apply the strictest version of the strong-password principles to that one password, and never reuse it anywhere else. It’s also worth checking now whether any password you’re currently using has already appeared in a breach — you can do that for free at PW Checkup.
