Can I trust the received email from the social network?

Question

OAuth

Hello! I do authorization with the help of social networks.
Is it possible to trust the data received by access_token?
For example, a user has allowed access to email... Can I immediately send him a message to the mail without fear that his email is not there... Or can I save the received data without pre-filtering?

Answer 1

Trust data from any third party service with oauth - no.
Trust specific social networks - instead of writing a question here, register with a specific social network and check if it checks your email, if it gives you an unconfirmed email, and if it allows you to change your email without confirmation. In any case, you will need it to test your site.

Answer 2

Not
