Password managers store credentials in an encrypted vault, generate strong passwords, fill them into websites and apps, and increasingly hold passkeys, one-time codes and secure notes. Organisations use them to give staff unique passwords per service, to share access to team accounts without sending secrets over chat, and to revoke access when someone leaves.
The design of the vault matters more than the location of the server. Look for documentation that explains what is encrypted on the device before synchronisation, how the master key is derived, what happens when a user forgets the master password, and what an administrator can recover. Recovery features and escrow are convenient but also give someone other than the user a route into the vault. Clients and browser extensions run in a hostile environment, so independent security audits and a clear disclosure process count. Migration is generally possible through export files, which are often unencrypted and must be handled with care.
When choosing a European option, ask for published audits, open-source clients, self-hosting options, support for single sign-on and directory synchronisation, and a transparent incident history. Products such as 1Password are common reference points for features.
