Can't access my telus email

Hello. I'm not sure what to do here...

I changed my telus email password and attempted to re login to my device with the updated email password,  and I get this message from Google:

You appear to have no security keys registered on your account, and won’t be able to sign in.

To sign in on this device, ask your admin about registering a new security key or choosing another second step for verification.

The issue is I have no other option and even trying on a computer doesn't work. 

What do I do to regain access to my email?
