Email verification codes: what they prove and how to handle them

A one-time code usually proves that someone can currently read a particular inbox. It does not prove their legal identity, and it should not be reused as a password or shared with a person who contacts you unexpectedly.

Before entering a code

• Confirm that you initiated the signup or login request.
• Check the service name and destination page, not only the sender label.
• Use the code only on the site or app where you requested it.
• Ignore unsolicited codes; they may indicate a mistaken address or an attack attempt.

Codes expire for a reason

Services commonly limit a code by time, number of attempts, and requested action. Requesting a newer code can invalidate an older one. If a code fails, return to the original service rather than following a link from an unknown message.

Automatic highlighting is only an aid

gettemp.email detects code-like number and letter sequences to make them easier to copy. The detector can miss a code or highlight an unrelated number. The message text and the requesting service remain the source of truth. The detected value is never sent to analytics or ad providers.

When not to use a temporary inbox

Do not rely on an expiring inbox for password recovery, financial access, or any account you expect to keep. Read the temporary-email safety guide before using one for a new service.
