I recently tried out a decentralized private messaging tool, it didn’t ask for my personal information to register.
Instead, it only asked me to create a username and set a password, after which it provided me with a mnemonic passcode. (I had never used a mnemonic passcode before, but I learned that it’s a web3 or decentralized type of thing.)
On their FAQ page says “The Mnemonic Passcode is your ONLY SOURCE of backup in a scenario where your device breaks down or becomes unusable due to any reason. In such cases, all you need is your Mnemonic Phrase to recover all your account information. It must be copied, screen-shotted, or written down and kept in a safe and secret place until it is needed.”
Does Mnemonic Passcode more secure than usual password? Plus, is there any other ways to keep you mnemonic phrase?
After having gone to solutions that allow for simple and seamless password sharing between users, it’s hard for me to go back. Last I checked, none of the Keepass solutions could really seamlessly share passwords and have them update in some fashion without manual user intervention. That being said, I used it for a long time in my Dropbox and then Own/Nextcloud before moving to a password service, Lastpass and then Vaultwarden after the Lastpass security fumbles.
