libpam-google-authenticator or authy is probably what you're looking for. To ensure you should be able to use these, I'd suggest looking up each package option and determining if they are available as aarch64.

I was facing the same problem. What i decided to do was get a Yubikey. They have an application for linux Yubico Autehnticator. Can't confirm yet that it works on PinePhone but i'm sure it can be made to.
This way i'm also not tied to a device. The totp codes are kept on the key not the app/device.
EDIT: Just also found out that it can be done using CLI so even if the gui does not get built for ARM i'm hopeful for the CLI tools.
gnome-authenticator runs fine in phosh on postmarketOS, it's only a bit annoying to add keys to it since the camera integration doesn't work.
Guys I just did manage to set up AWS MFA on PinePhone64 with OTPClient 2.6.3 on Mobian. They sent to me the qr code as image. I sent the image to the phone and I used the option for scanning QR from the image. There was also necessary to confirm my MFA installation and it all worked. I guess it will work with other providers as well.
