The keys and permissions — access, tokens, authentication. Who may open which door, recorded plainly.
The ability to reach and use a thing. Access is granted or withheld by someone, always.
Consent given by one with standing to withhold it. Approval is a gate, and a gate nobody could close is not one.
To give consent by one with standing to withhold it. Approval is a gate; a gate nobody could close is not one.
The establishing of who someone is and what they may do. Two questions bound together — identity, then permission.
Established as who they claim to be. Authentication settles identity and says nothing about permission.
The establishing that one is who they claim. Authentication settles identity and says nothing about permission.
The establishing of what one may do. Distinct from authentication, which only settles who they are.
Not permitted. Forbiddenness is a decision someone made and should say who.
To give something that was asked for, by the authority to give it. Its root is not gift but trust - to grant is to find the asking credible.
To hold closed against opening. A lock assumes a key exists and is held by someone.
The act of establishing who you are to a system. The threshold between anonymous and known.
A secret held so that knowing it proves who you are. A password protects only while it stays unshared.
Leave granted to do a thing. Permission implies someone had the standing to withhold it.
Held safe from reach or harm by something standing between. Protection implies a protector.
Row-level security — rules deciding which rows a given reader may see. Permission enforced in the data itself rather than above it.
A small thing standing for a larger right or meaning. A token carries authority it does not itself contain.
Acting without the standing to do so. Unauthorised is about permission, not about identity.
To remove what was holding a thing closed. Unlocking grants access that already existed behind the barrier.
To end a standing arrangement one had agreed to. The existence of this act is what made the agreement real.
