    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.

    andOTP is fantastic, but it's not cross-platform like Authy.

    It is one of the best 2FA alternatives that can be used on a PC. Authy is doing this on mobile because it does not have mobile support. On the PC, the Authenticator is the best option. Cloud support, encrypted backup, and a clipboard have features such as copying. There is also an automatic filling option for 2FA fields, but in some cases, it fills information on other fields.
