FAQ
Specific questions
Does the sender name prove who sent it?+
No. SMS, email and phone systems can be spoofed or made to imitate legitimate names and addresses.
Can my bank ask for an SMS code?+
Authentication codes are extremely sensitive. Do not give one to someone asking by phone or message; verify directly with your bank.
Should I reply to see whether it is real?+
You do not need to. It is safer to verify through an independent official channel.
