I find 2FAS to work great, especially with the browser extension.
Bitwarden authenticator is ok.
Avoid Authy.

Why avoiding Authy ?
Authy was the best product early on in 2013. Unfortunately, by late 2014 Twilio bought it and put it on a dying track. They didn't update the app for 7 years. Then they decided to make it part of their suite and eventually I lost confidence in what they were doing wit it.
