Suggest specific account to use for signing in with OAuth
With most OAuth providers you can add a specific account (email adress) as prefered account to use for the OAuth protocol. An example for Github: https://docs.github.com/en/apps/oauth-apps/building-oauth-apps/authorizing-oauth-apps
I am creating an account in advance before triggering an OAuth login to trigger some validation checks on the email domain. Locked account creation for the client, only possible with server side combined with the create user endpoint. I would like to send the email with the Oauth function, is that possible?
TL;DR
Suggest using a specific account for signing in with OAuth. You can add a preferred account (email address) for the OAuth protocol. It is possible to create an account in advance before triggering an OAuth login to validate the email domain. Combine server-side and create user endpoint for locked account creation. This is the flow for Microsoft: https://learn.microsoft.com/en-us/entra/identity-platform/v2-oauth2-auth-code-flow There you can send a login_hint but also a domain_hint as well.
