How do you implement registration with email confirmation?

Question

Django

Task: authorization by email + password, registration with confirmation by email, password recovery by email.
1) Use a ready-made solution. What is the de facto standard?
2) Saw your own. Whereas? Based on is_active? How and on what basis do you generate a token? Do you save the token in the database or generate it on such data so that you can repeat it when confirming? How can a user resend an email if it didn't arrive and the page with the resend link is closed?
