What to know before choosing

The single most important habit for password security is not the manager you pick, it is that every site gets a unique, generated password. Any vault on this list handles that.

Watch out for free tiers that limit devices: if a manager only syncs on one device, it will quietly break your workflow. Bitwarden and LastPass both sync unlimited devices for free.

Frequently asked questions

Are free password managers safe?

Yes — Bitwarden and LastPass encrypt everything locally before it reaches their servers, and both have been independently audited.

Can I use Chrome's built-in password manager instead?

Chrome's built-in manager is fine for basic use, but a dedicated vault adds breach monitoring, sharing and better cross-browser support.
