What Should I Do With an Unexpected OTP Email?
Handle a verification code you did not request without sharing or acting on it blindly.
Unexpected code? Treat that as context
If an OTP arrives for an action you did not start, do not share the code and do not follow the message blindly. First verify the sender, service and whether the address may have been entered by mistake.
Unexpected does not automatically mean attack
Someone may have mistyped an address, or a service may have retried an old action. But an unexpected code is still a reason to slow down because it represents an account action you did not initiate.
Do not give the code to anyone
A common social-engineering pattern is to trigger a code and then ask the recipient to forward it. Treat the OTP as private even when the inbox itself is temporary.
Use the message as context, not instruction
Open the message if you need to identify the sender, but avoid clicking unexpected links or entering the code anywhere unless you independently confirm why the verification exists.
The practical takeaway
An unrequested OTP should trigger verification of context, not a faster click.
