register more than one passkey

We are using devolutions server with devolutions password manager but are missing the possibility to register more than one passkey as a 2nd factor per user.

Please add the possibility to add more than one passkey per user. (all other methods like TOTP are not 100% safe from a security way and not user friendly if using more than one machine)

Your product is a password safe and as a password safe supporting the safest multifactor methods on a user friendly way should be your top priority.

Thank you very much!
