How to spot this (Text about an unusual login)

A random number, not a short code your exchange uses — and texts are easy to spoof.
The callback number connects to a scammer who will "help" by asking for codes or moving funds to a "safe wallet".

Remember: Don't call numbers or tap links in security texts. Open the app yourself and check your account activity there.
