Frequently Asked Questions

What is a CSRF token?

A CSRF token is an unpredictable value used to confirm that a state-changing request originated from the expected application session.

How long should a CSRF token be?

A token should contain sufficient random entropy. A value based on at least 128 random bits is commonly appropriate.

Is generating a token enough for CSRF protection?

No. The application must also store, send and validate the token correctly for protected requests.
