Just keep TOTP in your password manager at this point. Whatever security is lost by it not being a "true second factor" is made up for by not having to recover or restore backups due to a lost or stolen phone.

A password database file is sort-of a second factor (something you have).

Recently had a hard time exporting 20+ OTP secrets from Google Authenticator. I believe I discovered a bug in the app: if you long press a secret > edit > leave an empty string as the comment, and then export a QR code containing this secret, your other device will fail to import ("QR code cannot be interpreted."). I've only seen this happen with secrets where the comment is put in parentheses and appended to the reg…

There's a third option to switch from Google Authenticator to Aegis. You can simply scan those export QR codes of Google Authenticator with Aegis.

Wouldn't that need a second device since one can't screenshot Google Authenticator?

Correct.

Yubikeys store everything on the key. I can lose my phone and use your phone to see my 2FA codes. It's honestly one of the only way MFA make sense - otherwise you lock yourself out of your entire digital life when you lose your phone and need to rely on storing your backup codes (which opens up a storage security wormhole). It's also a lot easier to wear around your neck.

So you've moved the worry from losing/breaking your phone to losing/breaking your YubiKey?

Sure. I have a backup key but yes, you can't get MFA without adding a device that you may lose; whether that's your phone or a key. Like I said I prefer a key because I can't put my phone on a chain around my neck or on my keychain.

I keep a second key as backup for this reason, which honestly is overkill and I only do because I got a second one for free at a conference. Easier solution (which I also use in case I someday need the second one only to discover that the blue smoke leaked out) is to just print out the TOTP secrets and keep them somewhere. I'm usually printing out recovery codes when I get a new TOTP secret so this has never felt like a big deal.

Also easy enough to maintain a keepass[xc] vault for totp secrets, you could keep a separate one from your passwords if you were feeling paranoid. Great support on mobile and desktop for using a keepass db as a TOTP source - and easy to sync with dropbox/email/ssh/your web server/whatever

The killer feature for me is a way to quickly access tokens in my (cloud-side, encrypted) vault from a desktop (or web) app in case of emergency. It's not clear to me if Aegis allows this somehow? The other day I broke my phone. I was traveling and needed to do some 2FA level changes to a GH repo asap. I didn't even know there was an Authy desktop app until then. It saved my ass, literally.

The only downside is limited space on Yubikey.

I am currently carrying 2 tokens :(

who says you only have one or no other backup?

anyway I wouldn't but s Yubikey for TOTP. OTP sucks. Sure it's better than no 2FA and TOTP is better than SMS OTP still it's not grate.

WebAuthn-like auth can provide all the benefits of TOTP while being way more secure and in some cases even not convenient.

The main drawback is how to backup your 2FA which makes it less of a choice for a "casual" user.
