Authy sunset provision

[Rick Neifeld]

Colleagues - Authy is the 2FA Authenticator App I have used for years due to its end to end encryption sync-ability across platforms.
Today I received a "Desktop App Sunset Notice" in an update to Authy, noting a March 19, 2024 end of life for the Authy desktop authenticator app.  The mobile app on Android will continue to function. That means Authy would be limited to mye mobile Android (and for others to their Apply versions).

Do you have a recommendation for a replacement 2FA authenticator that syncs cross-platform (at least Windows and Android) and has end to end encryption? 

Twilio, Authy's owner, kindly suggested trying one of the following desktop authenticator alternatives.  I have not explored these alternatives; do not know if they sync cross-platform and have a mobile app version.

Any other comments in the 2FA issue are welcome. My concerns are security, usability, and reliability.  I have always been concerned with being locked out of a substantive online service as a result of the corresponding 2FA service becoming unavailable, which is what I consider a reliability issue.
