# Re-registering using your CoolApp PIN

The latest CoopApp updates introduce an optional way to re-register your CoolApp account on a new phone or reinstall CooolApp on an existing phone. Instead of waiting for an SMS code to arrive (and sometimes having to switch to a different app in order to see it) the new process is faster and easier, and it's just as secure too. Here's how it works:

CoolApp stores a token using the key-value data store on Android (if available), or the iCloud key-value store on iOS (if available).

This token, when combined with your CoolApp PIN, can prove that you were the most-recent owner of a given phone number, which lets us skip sending an SMS code. In other words, the combination of the token and CoolApp PIN can replace the SMS code.
The token itself does not provide any information about you or your account to anyone else, and it's only used for the purpose of enabling re-registration.



Note: If you cannot remember your CoolApp PIN, you can tap the “Skip” button in the top-right corner to go through the traditional SMS verification flow instead.
For those interested in a bit more information about the CoolApp PIN re-registration process:

Tokens are immediately invalidated if you or someone else goes through the registration process (e.g. by completing SMS verification).
They are also invalidated if you delete your account.
Only the last token that successfully registered with that number is valid.
The token is useless without knowing the correct CoolApp PIN.
Registration Lock isn’t affected by any of these updates. You only need to enter your CoolApp PIN once.
