expired code

An expired code is a code whose validity period has ended, so it is no longer valid for use.

In plain English

Some codes can only be used for a limited time. Once that time window ends, the code is expired. After that, it cannot be used anymore.

In context

Here, "expired code" reports that the entered MFA code was rejected because its allowed time for use had already ended.

Situation
Setting passwords, multifactor authentication, recovery codes, and trusted devices
What it communicates
reports why the entered MFA code was rejected

Meaning limits

By itself, the term does not say when the validity period ended or why the code was entered after that point.

Examples

“At noon the entry code still worked, but by evening it was an expired code.”

Core meaning

“When she entered the six-digit number, the app rejected it as an expired code.”
