Hi @akkivish47
Welcome to the Auth0 Community!
Thank you for posting your question. To edit the mentioned text, you need to go to Branding → Universal Login → Advanced Options → Custom Text.
Also the following screen asks for permissions even if I use an email/password combination.
I am not sure what these permissions and profiles are.
I assume you mentioned the Consent Screen, and there’s an option to disable that. Check our Knowledge Article about that → Disable the Consent Screen for Profile when Logging into Auth0 Applications
Thanks
Dawid
