Perhaps you need to keep notes (paper) for those details..

Since you may need to use 2FA with your Google Account

and Gmail among others. ~ And use a computer to login.

I do and so I also have several layers of notes; sometimes

I can skip and use newer steps. ~ However online security

for banks & insurance, often has their own too; I've found.

And I hate having to get my phone out and turn it on, to

further their Two Factor B.S. since most security now is

more trouble, yet seems to be not truly secure!!

Their ideas now include use of Devices, too.

I gave up on Apple Mail & Siri; and login by browser often.

You can use a standard web browser and login to Google.

Their main portal takes you directly into Google Accounts.

This gives me a headache; so much so, that I've lost track!

Google might send an email and try your phone, to confirm.

As a fellow user, with older iPhones and non-current Macs

there's lots of newer stuff that won't work here. Cheers!
