Another problem is some clients like Amethyst only let you export your nsec but not the mnemonic words and some tools like Alby's browser extension only let's you import mnemonic words but not your nsec. 

 Our extension definitely let's importing your nsec! Just paste it it Nostr settings and then following NIP-07 it signs your notes locally! 

 The friendly neighbourhood bee comes buzzing. I'll try that, thanks!
