What is a password generator?

A password generator creates strong random passwords with your chosen length and character sets. Passwords are generated locally and are not stored.

Private on your device

Create strong random passwords using secure random generation. Choose length and include uppercase, lowercase, numbers, and symbols. Optionally exclude ambiguous characters for complex passwords that are easier to type. Passwords are never stored.

Generated passwords are only as secure as how you store them. Copy into a password manager immediately and avoid saving secrets in plain notes or chat logs. Exclude ambiguous characters when the target system rejects them.

Password generation uses secure random generation on your device. Nothing is sent to Utilnivo servers. Rotate passwords after vendor breaches even when the old password was strong.

For Wi-Fi passwords you must read aloud, favor longer passphrases with words and digits rather than short random strings.

Sites that cap length at 16 characters need shorter outputs—raising length here does not help if the destination form truncates silently.

Developer test accounts can use separate generated secrets per environment so a leaked staging password never unlocks production.

Memorable master passwords for password managers can be long passphrases generated here once, then used only to unlock the vault that stores everything else.

Regenerate if the password appeared on screen during a screen share—treat displayed secrets as compromised.

NIST guidance favors length over forced symbol rotation every 90 days—use 16+ characters unless a site policy requires symbols.

How to use this tool

1. Set password length and character sets (uppercase, lowercase, numbers, symbols). 2. Click Generate. 3. Copy the password into your password manager immediately. 4. Regenerate if you need a different pattern.

Worked example

Example: 16 characters with all sets enabled yields a strong random password—Utilnivo does not store it.

When to use this

  • Creating a unique password for a new SaaS account.
  • Rotating API keys or staging credentials.
  • Generating PIN-free passwords for legacy systems with character rules.
  • One-time strong strings for Wi-Fi or PDF encryption.

Common examples

  • 16-character password with symbols for a new SaaS admin account → copy into a password manager immediately.
  • 24-character passphrase-style random string for API key rotation in staging.
  • 12-character PIN-free password excluding ambiguous characters for legacy systems.
  • 20-character admin password with symbols for staging database root (store in vault).
  • 16-character Wi-Fi passphrase without ambiguous O/0 characters for guest network poster.

Common mistakes

  • Reusing generated passwords across multiple sites.
  • Copying without saving into a password manager first.
  • Choosing length too short for high-value accounts.
  • Disabling symbols when the target site actually allows them.

How it works

Passwords are generated on your device using secure random generation. You choose length and character types. Ambiguous characters can be excluded. Generated passwords are not stored or sent to a server.

FAQ

Frequently asked questions

Are generated passwords stored?

No. Passwords are generated on your device and are not logged or sent to a server.

How is randomness generated?

The generator uses the secure random generation for strong randomness.

What are ambiguous characters?

Ambiguous characters include look-alikes such as 0, O, 1, l, and I. You can exclude them for easier reading.

What makes a strong or complex password?

Length plus mixed character types. Prefer 16+ characters with uppercase, lowercase, numbers, and symbols, and avoid reused or guessable phrases.

Password generator vs passphrase?

A password generator builds random character strings. Passphrases use several random words. Both can be strong; use a password manager either way.
