OAuth server, should I store user access_tokens?

Question

OAuth

Dear users, the task arose to implement your own OAuth server.
Question. Is it necessary and possible to store the issued access_tokens of users at home? Those. store the current token for each user. And when the user gets a new one (using a refresh_token or by hand), overwrite it.
Otherwise, how to make it so that for each user there is always only one working access_token?

Answer 1

I will answer my own question, which I also asked on stackoverflow.
Yes, access tokens are stored on the server, it is the responsibility of the server to store the actual user tokens.
