Be careful with those screen shots Phil. I just had my SIM card ported and my email/coinbase account passwords reset. Coinbase's default 2FA authentication goes to your phone and your email is security is also garbage if its 2FA is also your phone. I guess they upgraded my coinbase (which was basically unused) to coinbase pro and I guess that gave them instant access to all crypto on the account. Drained my bank account to coinbase and transferred it out to their address in less than 30 minutes...
coinbase can use yubikeys now. and trezors can be configured as yubikeys as backup.
highly recommended. nothing moves off exchange without the yubikey.
