Standard Notes makes use of end-to-end encryption to encrypt your data on your device before it's sent to our servers. This means that we, or anyone else, cannot read the contents of your notes, nor do we know what your encryption key is. For this reason, password resets are simply not possible. In most cases, your only option is to delete your account by following the reset instructions, then start over in a new account.
However, if you're still signed into your account on any device it's still possible for you to export a decrypted backup of your data from that device. That way, you won't need to start from scratch on your new account.
Once you've exported a decrypted backup file, you can import it into a new account using the Standard Notes application.
