Password managers are pretty much required now. We need so many passwords, and weak passwords are the easiest way to get compromised.
Here’s one way to use Nextcloud and password managers.
You’ll need: a database, think of an old school spreadsheet that has the passwords on it (but safe and encrypted). That is your database. You also need a ‘safe’ that those passwords are stored in. That can be either: using a program (like KeepassXC)*recommended or storing them inside your Keeweb App (not recomended because you don’t have access offline).
Memorize only one main password to open your safe, and all the passwords inside that safe are long and computer generated passwords (and different from each other).
