The site makes some very bold claims ("The Safest Password Manager"), but most of it seems pretty standard fare for password managers. Also am I reading it right that backups and unencrypted and it is left up to the user how to handle them? Or if they are encrypted how do I unlock them on a new phone if I don't have access to the old one (if it was lost/destroyed)?
“Show HN” means OP is the maker of that project, am I right? In that case, isn’t it extremely suspicious that OP claims “great security design” in the title?
