Private by design

Password generation happens on your device. Toolmivo does not need to upload generated passwords to a server.

How it works

Create a strong password in seconds.

Choose a length, select the character types you need and generate a fresh password. For important accounts, longer unique passwords are generally safer than short or reused ones.

Choose your settings

Pick the password length and decide whether to include uppercase letters, lowercase letters, numbers and symbols.

Generate securely

The generator uses browser cryptographic randomness and creates the password directly on your device.

Copy and store safely

Copy the password and save it in a trusted password manager instead of reusing it across multiple accounts.

FAQ

Password Generator FAQ

Does Toolmivo save generated passwords?

The generator itself works locally in JavaScript. Generated passwords are not required to be sent to a server, and the alternative password list is cleared when the page is refreshed.

How long should a strong password be?

There is no single perfect length for every service, but longer unique passwords provide more possible combinations. A 16–20 character random password is a practical strong default when the website allows it.

Why exclude similar characters?

Characters such as I, l, 1, O and 0 can be hard to distinguish when a password is typed manually. Excluding them can improve readability without changing how the generator works.

Is this better than using the same memorable password everywhere?

Unique passwords reduce the damage if one service is compromised. A password manager can help you store different random passwords for different accounts.
