Password Generator

How the password generator works

Our password generator creates random, secure passwords instantly, tailored to what you need. You can choose the length and which character types to include, and a bar shows the strength of the result. Everything is generated in your browser with a cryptographically secure generator, so passwords are never sent to any server.

The tool gives you full control over the password you create:

• Adjustable length: choose how many characters your password will have; the more, the safer.
• Character types: turn uppercase, lowercase, numbers and symbols on or off.
• Strength indicator: a bar shows instantly whether the password is weak, medium or strong.
• Secure randomness: it uses the browser's cryptographic function, not simple predictable chance.

How to use the generator

1. Adjust the desired length with the slider.
2. Check the character types you want to include.
3. The password is generated automatically; tap to create another if you like.
4. Copy the password with one tap and store it somewhere safe.

Length and entropy: why they matter

A password's security depends above all on its entropy, that is, how many possible combinations it has. Each extra character and each character type (uppercase, numbers, symbols) multiplies those combinations, making it far harder to guess by brute force. That's why a long, varied password is much safer than a short one, even if the short one looks complicated.

What a strong password is for

• Protecting your accounts: email, social media, banking and online shopping.
• Avoiding reuse: a unique password per service stops one leak from affecting the rest.
• Resisting attacks: long, random keys are nearly impossible to crack by brute force.
• Critical accounts: especially your main email, which usually recovers the others.

Tips for managing your passwords

• Use a password manager so you don't have to memorize them all.
• Don't reuse the same password across several sites.
• Turn on two-factor authentication (2FA) whenever possible.
• Immediately change any password that appears in a data breach.

Privacy: they're generated in your browser

Passwords are created entirely on your own device using the browser's cryptographic generator; nothing is sent to any server or saved anywhere, so only you see the result.

Common mistakes when choosing passwords

Many passwords are insecure due to easily avoidable mistakes:

Most frequent mistakes

• Using personal data: names, birth dates or your favorite team are easy to guess.
• Obvious sequences: "123456", "qwerty" or "password" are among the first ones tried.
• Reusing the same key: if it leaks on one site, all your accounts are exposed.
• Passwords that are too short: however odd it looks, a short one is cracked quickly.
• Predictable substitutions: swapping "a" for "@" or "o" for "0" adds barely any real security.

Password managers and two-factor authentication

The most practical way to have strong, different passwords for each service is to use a password manager: it generates and stores complex keys for you, and you only need to remember one master password. Combine it with two-factor authentication (2FA), which adds a second factor —like a temporary code— so that even if someone knows your password, they can't get in without that second step.
