I personally use andOTP [0] which I'm a fan of. I've been thinking of switching to aegis [1] for nothing more than a UI change.

I never had any issues with andOTP. It worked even when some websites specifically asked for a different app.

The integrated TOTP in 1Password is pretty good, it can grab the QR code off the screen and everything.

Just be careful with these solutions, I use the one in Bitwarden for a few things and while great for convenience, there's a significant security tradeoff when you go ahead and load all your TOTP tokens into memory on the same machine you keep the passwords on. Turns your 2 factor authentication into single factor pretty fast against even a decent piece of malware, let alone a dedicated attacker.

Microsoft Authenticator is good, and there’s a reasonable chance they already use it at work.

Google Authenticator seems fine?

Google Authenticator ?
