I use yubikey everywhere it's available for me. Initially, the first few websites in the early years were challenging. I think a lot of devs were still trying to figure out the workflow.

But today, it's usually as simple, or simpler, than TOTP.

So it might be worth trying again. I'd use a YubiKey 4 or higher if you can. If you have an older one, you may want to upgrade to take advantage of the newer technology like NFC and Bluetooth if you're into that.

I just wish YubiKey could store more than like 30 TOTP tokens.
