What happens if I delete my app and don't have my recovery password?
If you have lost access to your Session Account and you do not have your recovery phrase (13 words) noted then you will have lost that Account ID.
The only way to restore an Account ID is through this recovery password, not even we can help.
If you have found yourself in this situation then you're only option is to start again with a new Account ID. This time, please remember to take note of your recovery password.
