Once the 48 hours have passed, the token will be deleted from all the devices and our servers.

Note: If you try to delete a token that is encrypted, you will receive a warning advising that the token will be permanently deleted. Once you accept to delete the token, the encrypted copy of the token is deleted from our servers. If you accidentally deleted an encrypted token, you need to contact the service for which you had the token to regain access to your account.

We regret to say that once the tokens are deleted from the device and from our servers, we can’t recover the tokens.
