Trying to sign in to my Gmail account without success

I see but I don't have any passwords stored on my phone/cloud mine are written down in my desk diary

You need a "keychain", or equivalent that stores your passwords.

I only know the passwords that unlock my phone and my laptop. Then face recognition and fingerprint do the rest.

If I need to see a password I sign into my iCloud. Android will have something similar.

Thanks Baggs. There are options to change password etc but it doesn't help. I just have new passwords to remember but am still locked out. I can't even explain it properly.

Have you tried this Grammaretto,
If your account is disabled, you can ask Google to restore your access. To get started, head to myaccount.google.com and enter your Gmail address. Tip: If you can't get in to your account, you may be able to download and save account data from some Google Services.
Good luck with it.

The messages from GGL should not be going to your gmail address. Do you have another email address that you haven't used for a while?

Usually there is an option to change password/username.

But perhaps I have misunderstood.
