Why an OTP may be delayed

A verification code can be delayed by network conditions, message filtering, an incorrect registered number or a temporary service issue. Check the contact details shown by the platform before requesting another code.

If an OTP has expired

Request a fresh code through the current verified login or registration flow. Use the newest valid code and do not rely on an older message.

OTP security

An OTP is a private verification credential. Never send it to a person claiming to be support, an agent or a payment helper, and never read it aloud to someone who contacted you unexpectedly.
