limit amount of authentication tokens

[cyril moreau]

Hi,

I would like to know if there is a way to limit the amount of token that a user can create?

I am using django-oauth2-toolkit to generate the token.

The user can hit the auth url  (http://localhost:8000/o/token/) as much as he wants and creates a new token everytime he goes to that url. 

This action will fill up my database with new valid token.

How can i limit this token creation?

Should i limit this token creation? (like allowing 10 tokens by users to be able to log in my app from different devices)

Thank you for your help.
