I gave someone a verification code. What should I do?

1. Read the original code message to identify the service. Open that service directly and contact its official support.
2. Change the affected account's password, end unfamiliar sessions, and check recovery details and recent activity.
3. For a bank code, call the bank's fraud line now. Explain exactly what you shared and which transfers you did or did not initiate.

You lose account access, find new devices, or see transfers. In the US, sharing a code does not automatically erase fraud protections.
