    BitWarden can be used for TOTP, but it's not included in the free version. So comment from @josephcw and @gholem is not true. See: https://bitwarden.com/pricing/

    Authy is a one-time password generator for 2FA whereas Bitwarden is a password manager.

    It's open source, uses harder encryption and you can migrate between devices.

    Leaving a negative comment, not because Aegis is bad, but because it's still not a good competitor/alternative to everything Authy offers in terms of convenience (iOS app, and desktop/Windows app). With these two, Aegis would NO DOUBT be the best out there.

    I chose it because it is private, open, simpler and versatile, in my opinion

    Ente is miles better than most 2fa services atm and is completely open source and ad free

    Not to mention it now has proper cross device support with its own desktop application, following authys own 2fa being discontinued

    Really happy with this dev team imo the best 2fa service you can get atm

    FOSS alternative to Authy with mobile and website token sync. Can also import/export keys. Only question is how long Ente will keep the service free.
