what is the expiry time of github oauth access token. And also how do I renew it. I don't see any refresh token in their documentation. Please guide me. Thanks in advance.
2014: As commented in this "GitHub OAuth Busy Developer's Guide"
Tokens don't have to expire.
They only send back the access token and an expiration (field "expires_in", seen as far back as 2013) if theoffline_accessscope is not requested (as it is the case for a refresh token).
Right now, GitHub just assumes all apps want offline access.
You can check an OAuth application authorization, delete it or revoke it.
But the token itself doesn't seem to be bound to an expiry date unless they are not use for one year.
badsyntax adds in the comments:
I also found this useful:
"An OAuth token does not expire until the person who authorized the OAuth App revokes the token."
From "Migrating OAuth Apps to GitHub Apps".
Stokito points out in the comments to rfc6749 / 4.2.2 Access Token Response:
expires_inRECOMMENDED.
The lifetime in seconds of the access token.
For example, the value "3600" denotes that the access token will expire in one hour from the time the response was generated.
If omitted, the authorization server SHOULD provide the expiration time via other means or document the default value.
