FAQ
Password generator questions
Everything about creating and managing strong passwords.
Is this password generator truly random?+
Yes. This tool uses your browser's built-in cryptographically secure random number generator (window.crypto.getRandomValues), the same API used by security software. Your passwords are generated entirely in your browser and never sent to any server.
Are my generated passwords stored anywhere?+
No. Passwords are generated locally in your browser and never transmitted or stored anywhere. Once you close or refresh the page, they're gone. Toolum has no servers receiving your passwords.
How long should my password be?+
At minimum, 12 characters for general accounts. For sensitive accounts (banking, email, work), use 16+ characters with uppercase, lowercase, numbers, and symbols. Password managers make long random passwords easy to use — you only need to remember one master password.
What makes a password strong?+
Strength comes from two things: length and character variety. A 16-character password using all character types has over 100 bits of entropy — effectively uncrackable with modern hardware. Avoid dictionary words, names, dates, and keyboard patterns like 'qwerty' or '123456'.
What is a passphrase and when should I use it?+
A passphrase is a sequence of random words (like 'correct-horse-battery-staple'). They're easier to remember than random characters but still very strong because of their length. They're ideal for master passwords, disk encryption, and anything you need to memorize.
Should I use a password manager?+
Yes, strongly. A password manager lets you use a unique, long, random password for every site without memorizing any of them. Popular options include Bitwarden (free, open source), 1Password, and Dashlane. The only password you memorize is your master password.
