Adding to Nadine response A token might stop working for one of these reasons: 1) The user has revoked access. 2) The token has not been used for six months. 3) The user account has exceeded a certain number of token requests. There is currently a 25-token limit per Google user account. If a user account has 25 valid tokens, the next authentication request succeeds, but quietly invalidates the oldest outstanding token without any user-visible warning.
