> so I can't log into GPM (2FA requires the phone) Use one of your backup codes?
I could be mistaken, but it was my understanding that those backup codes are one-time-use only, and that using one basically burns it forever. My cookies get cleared every single time I close my browser, so I would have to continually log back in and keep burning more codes. If I'm wrong about this... that would be excellent.
It's inconvenient, but if your in an environment that disallows phones or other portable electronics (like 2FA Fobs/USB sticks), it may be the only reasonable way.
