My site utilizes lifetime access tokens (offline_access). However, if the user changes his/her password, the access token gets reset. Is there a method to check if the current access token is valid before making calls to the Graph API? Thanks for your time.
Is there a way to check if Facebook access token is still valid?

I went through these posts, bud I found very good solutions like this:
GET graph.facebook.com/debug_token?
input_token={token-to-inspect}
&access_token={app_id}|{app_secret}
Response from this request provides you everything you need:
- your app ID - this verifies that token is from your application
- application name - which can be also checked
- expires_at - token expiration time
- is_valid - boolean for check up
- user_id - which you can also compare and check
Just note that "|" sign must be there as a letter
