Best European Alternatives to Microsoft Authenticator (2026)

Microsoft Authenticator backs up your codes to your Microsoft account, under US law. Microsoft has also been removing features from it, such as saving passwords. European authenticators give you the same codes with an encrypted backup you control.

Replace Microsoft Authenticator with a private authenticator app based in Europe. Compare Proton Authenticator, Yubico Authenticator, Proton Pass, all operated under European privacy law.

Proton Authenticator (Switzerland) Free app for your login codes, on phone and computer. Works without an account; with a Proton account you get an encrypted backup.

Yubico Authenticator (Sweden) Keep your login codes on a small key from Swedish Yubico. The app is free; you buy the key once.
✓ Open source
Proton Pass (Switzerland) Password manager from Proton that also generates private email aliases so websites never get your real address.
✓ Open source ✓ Audited ✓ Free tier
