How to do password recovery without database in php?

Question

PHP

Hello. I made a mail change for the registered user, sending the code to the database and to the mail, then I check if it is the same, then I change the mail.

Now you need to do a password recovery if the user is not even logged in. Accordingly, we do not have access to the database, there is no session, where can we save this confirmation code to confirm?

Answer 1

Accordingly, we do not have access to the database

In sense, access to a DB is not present? Get a separate sign, write user_id, code and date there.
