Is it possible to increase the validity of access token for REST Apis

I've logged the current duration for review:

Note that we are also considering implementing PKCE to support apps which cannot maintain client secrets:

Hi Ben,

Is there any patch for 11.1.0.9731, or else do we need to upgrade?

The resolution for 11.1.x is in 11.1.7. There is not another method to receive this update for 11.1.x.

we found that the validity time is increased from 1 hour  to 24 hours in 11.1.7,

Is there a way to use refresh tokens for this grant type?

Refresh tokens require the client secret. For clients that cannot securely store a secret, the PKCE work (when implemented) will enable an alternative and enable refresh tokens.
