What is PKCE (Proof Key for Code Exchange)?
Proof Key for Code Exchange
PKCE checks that the connection collecting a sign-in token is the one that started the approval process.
In a Bangladeshi restaurant
During a restaurant connection, the assistant supplies proof that Rosuii checks before exchanging the approval code for a token.
Common mistake
PKCE does not decide which restaurant records a staff member may read; account permissions still matter.
Where it lives in Rosuii
Rosuii requires this check in its OAuth connection flow without asking the owner to copy the proof values.
