mod_http_oauth2: Shorten default token validity periods With refresh tokens, short lifetime for access tokens is not a problem. The arbitrary choice of one hour seems reasonable. RFC 6749 has it as example value. One week for refresh tokens matching the default archive retention period. This means that a client that remains unused for one week will have to sign in again. An actively used client will continually push that forward with each used refresh token.
