Secure Password Generator

Q: What is the minimum size a secure password should have?

A minimum of 12 characters is recommended for general use and 16 for corporate environments. Longer lengths increase entropy and make brute force attacks more difficult.

Q: Why avoid similar letters and numbers?

Removing ambiguous characters reduces typing errors without compromising security, as the remaining set is still broad.

Q: What is the best way to store generated passwords?

Store passwords in reliable managers or corporate secret vaults. Avoid spreadsheets and physical notes.

Q: Does the generator save the created passwords?

The generator works entirely in the browser and does not save or send passwords to servers.

Q: How to implement password policies in the company?

Implement policies with minimum size, mandatory character types, expiration, and MFA. Use e-mail and CPF validation tools to complete onboarding.

Create strong passwords with custom criteria, copy with one click, and apply best practices in corporate policies and online registrations.

Benefits

• Instant generation without server dependency.
• Criteria aligned with NIST and PCI recommendations.
• Ideal for secure onboarding in your digital product.

Complementary tools

Why strong passwords matter?

Brute force attacks and database leaks continue to be the main entry point for intrusions. Short and predictable passwords are broken in seconds by automated scripts. By creating long and varied combinations, you exponentially increase the effort required to decipher access.

This generator uses a base without ambiguous characters to make viewing simpler without compromising entropy.

Updated NIST recommendations

NIST's SP 800-63B guidelines suggest long passwords, without arbitrary complexity, combined with multi-factor authentication. Avoid expiring passwords too often and prioritize checks against compromise lists.

• Recommended minimum: 12 characters.
• Passwords longer than 16 characters are ideal for critical accounts.
• Never reuse the same password on different services.

How to measure the strength of a password

The estimated strength indicated by the tool considers the theoretical entropy (bits) based on the size and the size of the character set. It does not replace anti-fraud solutions, but provides a useful indicator for internal policies.

Combine with leak monitoring (haveibeenpwned, corporate services) to quickly revoke exposed credentials.

Frequently asked questions

Best practices for creating, storing, and rotating passwords.

What is the minimum size a secure password should have?+

For personal accounts we recommend at least 12 characters. Corporate environments, especially those with access to sensitive data, should adopt 16 characters or more. The greater the length combined with different types of characters, the greater the entropy and protection against brute force attacks.

Why avoid similar letters and numbers?+

The generator removes easily confused characters (O, 0, l, 1) to reduce typing errors and facilitate reading in verbally communicated passwords. This does not reduce security, as the remaining set remains broad enough.

What is the best way to store generated passwords?+

Use a reliable password manager with end-to-end encryption. Avoid shared spreadsheets or physical notes. In corporate environments, adopt secret vaults with access control and auditing.

Does the generator save the created passwords?+

No. Everything happens in the browser and no password is stored or sent to servers. This ensures total privacy during the generation process.

How to implement password policies in the company?+

Define minimum length, mandatory character types, scheduled expiration, and multi-factor authentication. Educate employees with guides and combine the tool with the {validadorEmail} and {validadorCpf} for complete registration flows.
