About Password Generator

Create strong random passwords for accounts and apps. Password Generator on TheToolss lets you set the length up to 128 characters, toggle which character sets are used, exclude ambiguous lookalikes such as l, 1, I, and O, and copy the result in one click. A live strength meter updates with every change so you can see what length actually buys you compared with adding symbols. Randomness is generated on your device and nothing is transmitted, which is the only sensible arrangement for a credential you intend to use.

How to use Password Generator

Choose length with the slider or presets (12, 16, 24, 32).
Toggle Uppercase, Lowercase, Numbers, and Symbols.
Optionally exclude ambiguous characters (I, l, 1, O, 0).
Copy the password or generate a new one.
