It is extremely important to save your seed words somewhere secure. These are the same as a password and should not be given out to anyone. In the event that you lose your seed words, you will not be able to recover them. Open Librarian does not store a copy of your seed words.

Your NSEC is your Secret Key, it is geneated from your Seed Words and can be used to login to Open Librarian and other Nostr powered applications.

Your NPUB is your Public Key, it is generated from your NSEC and can be used to share your profile with other users.
