Hi everyone,

You can now securely log into your Proton Pass account on iOS and Android using FIDO2 (such as security keys) for two-factor authentication (2FA).

Here’s how: https://proton.me/support/set-up-fido2-on-mobile

What’s next?

Support for FIDO2 in other Proton apps coming soon, as well as the ability to disable the authenticator app when security keys are enabled.

Let us know what you think.

You can also propose, vote, and discuss feature requests on User Voice.
