Secure Password Generator — Strong Random Passwords Free

Create strong random passwords instantly with our free password generator on XConverters. Set length from 8 to 64 characters, toggle lowercase, uppercase, numbers, and symbols, then generate cryptographically random strings using crypto.getRandomValues — entirely no seu browser. Sem conta, sem carregamento, completamente gratuito.

O que esta ferramenta faz

Weak and reused passwords remain the top cause of account compromise. A dedicated generator produces unique, high-entropy strings you would not invent manually. Our tool uses the browser crypto.getRandomValues API — the same source of randomness trusted by security-sensitive web applications — not predictable Math.random output.

Length controls how many characters appear in each password, from 8 (minimum practical) up to 64 for API keys and long passphrases. Checkboxes let you require lowercase letters, uppercase letters, digits, and symbols so generated passwords satisfy typical site complexity rules. You can enable all sets for maximum entropy or restrict to alphanumeric when symbols are disallowed.

Passwords are generated locally on XConverters. Nothing is sent to a server, logged in a database, or stored after you leave the page. Copy the result into your password manager and close the tab — free with no registration, ideal for personal accounts, staging credentials, and one-time setup tokens.

Como usar

Generate secure passwords on XConverters:

1. Abra o Password Generator on XConverters — free access with sem registo.
2. Set password length using the control — choose any value from 8 to 64 characters.
3. Enable Lowercase if the password must include a–z letters.
4. Enable Uppercase if the password must include A–Z letters.
5. Enable Numbers if digits 0–9 are required by your target service.
6. Enable Symbols if special characters like !@#$ are allowed and desired.
7. Click Generate to produce a new random password using crypto.getRandomValues, then Copy to your clipboard.

Random bytes are drawn and mapped to your selected character sets entirely in the browser. XConverters never sees or stores generated passwords.
