   Bitwarden vs Authy Comments

   Top Positive Comment by Olav · Jul 16, 2021

   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/

   Top Negative Comment by RemovedUser · Oct 25, 2019

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

   Negative comment by Slaven · Jul 31, 2022

   Bitwarden has 2FA but it's not available in the free version.

   Aegis Authenticator vs Authy Comments

   Top Positive Comment by erebosgr · Feb 17, 2020

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

   Top Negative Comment by rustPunk · Jan 10, 2023

   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.

   Positive comment by Violeta Carrasco · Jun 24, 2024

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

   Ente Auth vs Authy Comments

   Positive comment by kurifoxen · Apr 2, 2024

   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

   Positive comment by Medi22 · Jan 9, 2024

   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.

   Positive comment by nayote · Aug 6, 2024
