- If you are a user of Facebook, then you must have come across the error validating access token.

Facebook may have been in the game for a while now, but that doesn’t exempt it from the usual errors that make it hard to access the app. You may get an error validating access token message, making it impossible to log in.
Access tokens are typically used for authentication in the Facebook API. The user must authenticate the request, so something must be wrong if the token cannot be validated. Let’s dig deeper and find out what this means and possible solutions.
What is Facebook you must provide an access token?
A Facebook access token is a short-lived token that allows an application to access your Facebook account.
It’s a random string of characters that identifies your user account and allows Facebook to tell whether it’s the real account, or a fake one.
When you authorize an application to access your data, the application can get a list of permissions you’ve granted it. For example, you may have given an application permission to post on your behalf.
If you’ve ever been asked to log into Facebook again after taking a break from using it, it is because cookies usually expire after a short period. This is one of the reasons you may encounter the error validating access token message.
Other reasons include:
- Change of passwords – If you’re logged into different devices and change your password, Facebook may require you to verify your credentials again to validate the access token. The message may be error validating access token: the session has been invalidated because the user changed their password.
- Invalid token – Just as we mentioned, the access token is short-lived so if you don’t use it within the specified time frame, it may have expired hence no longer valid. In such cases, you may get the error validating access token: session has expired facebook message.
- Revoked access – The user may have revoked the application’s authorization to access their Facebook account.
- App violation – It is possible that the application requiring the access token has been flagged and disabled for violating Facebook’s Terms.
