That feels like a lot, and is starting to get unmanageable.
I also have a handful of services tied to a Yubikey. But I've no way of knowing how many.
So, how many do you have?
The things I hate about the 2FA process:
1) requiring a phone number, especially only having SMS for 2FA like my foreign bank (I've reported the issue with SIM swapping with them on support and in person, but considering their system still isn't UTF using a very old encoding so I can't even type a comma in a message without errors, I'm not holding my breath)
2) not offering WebAuthn, especially as a big firm
3) Supporting specifically Yubikey and not FIDO2/WebAuthn
4) using some bullshit closed-source wrapper around TOTP like Symantec VIP that doesn't have a Linux client and requires me to use some random Python script to get spoof a Mac system to get a code (thanks Schwab)
I personally like to keep it in my iCloud account because I don't trust myself with keeping a private key for too long.
One service I use has four separate 2FA tokens to use with different service functions, and I have one account for me and one for my wife, so that single service accounts for 8 of 21 Authy tokens.
Password-store features git push and pull so I keep my encrypted passwords and TOTP keys on a couple remote Git servers. Because I use passwords that I don't know for every service, the Yubikeys are really more about being a safe way to back-up and transport my encryption key. If I've got that, I can always decrypt my passwords.
I also have a handful of yubikeys for more secure things.
I try to avoid 2FA. I have other strategies around account compromise.
More via phone number 2FA as well!
And a lot of passwords saved.... my app doesn't give me a count. Probably need to look on desktop :-)
They are getting a bit hard to handle mostly because my app (authy) doesn't have a good enough set of icons
Unrelated but no joke I have something like 600-700 accounts stored in LastPass
Well, two, technically, but I'd lost them long ago.
Mostly cloud services, version control, email.
