You can use any phone number that can receive text messages; it doesn't need to be associated with your account.
We won't use or give out the phone number, and the code sent to it will expire after 10 minutes.
This means you could use a friend or work colleague's phone without compromising your account security.
The quickest way to get your account unlocked is by requesting and entering a security code online. If you hen't tried unlocking your account online, we recommend you start there.
Tip:聽If your security code doesn't work, make sure you enter the numbers in the body of the message, and not the numbers in the header.
If you see a "usage limit exceeded" error message when requesting a security code, this could mean the phone number has been used too many times in a short period of time, or that we've detected something suspicious about the phone number.
