🔐 Password Security Tips

1

Never Reuse Passwords

Using the same password across multiple accounts is one of the biggest security risks. If one site gets breached, attackers can access all your other accounts automatically.

2

Use a Password Manager

Tools like Bitwarden, 1Password, or Dashlane let you store unique, complex passwords for every site without needing to memorize them all.

3

Enable Two-Factor Authentication (2FA)

Even if your password is compromised, 2FA adds a second layer of protection — a code sent to your phone or generated by an app — that stops attackers cold.

4

Longer is Stronger

A 16-character password is exponentially harder to crack than an 8-character one. Aim for at least 12–16 characters, especially for important accounts.

5

Avoid Personal Information

Birthdates, pet names, and common words are easy targets. Attackers use social engineering and dictionary attacks that can guess these within seconds.

6

Change Passwords After a Breach

Check services like HaveIBeenPwned.com regularly. If any of your accounts appear in a data breach, change that password immediately.

7

Beware of Phishing

No legitimate company will ever ask for your password via email or text. Always log in directly through the official website, not through links in messages.

8

Use Different Emails Too

Consider using separate email addresses for important accounts (banking, work) versus throwaway signups. This limits exposure if one address is compromised.

9

Log Out on Shared Devices

Always log out of accounts when using a public or shared computer. Saved sessions can be exploited by anyone who later uses the same device.

10

Keep Your Devices Updated

Security patches in OS and app updates close vulnerabilities attackers exploit. An outdated device can undermine even the strongest password.

❓ Frequently Asked Questions

Are my passwords stored anywhere?
No. PasswordAndLock runs entirely in your browser. No password you generate is ever sent to a server, logged, or stored. Once you close the tab, everything is gone.
How random are the generated passwords?
Passwords are generated using window.crypto.getRandomValues(), the browser's cryptographically secure random number generator. This is far stronger than Math.random() and suitable for real-world password generation.
What is the difference between Password, PIN, and Memorable?
Password generates a random mix of your chosen character types. PIN generates digits only — great for numeric codes. Memorable combines real words to create something easier to recall while still being long enough to be secure.
What length should I use?
For most accounts, 16 characters is a solid choice. For highly sensitive accounts (banking, email), go for 20+. PINs are typically 4–8 digits depending on the service's requirements.
What does the Health Checker measure?
It checks 8 criteria: minimum length (8 and 12 characters), presence of uppercase letters, lowercase letters, numbers, and symbols, absence of common patterns (like "123" or "password"), and absence of repeated characters (like "aaa").
Can I edit the generated password?
Yes! Click the ✏️ Edit button to unlock the password field and type any changes you like. The strength meter and health checker will update in real time as you type.
What is the Batch Generator for?
Batch mode generates 3, 5, or 10 passwords at once using your current settings. You can copy any one you like, or click "Use" to send it straight to the main generator field.
What is a Passphrase?
A passphrase is a sequence of random words joined by a separator (e.g. tiger-ocean-bread-7291). They are long enough to be very secure, yet far easier to remember or type than a random string of characters. Great for master passwords or accounts you log into often.
Is this tool free?
Yes — completely free, with no ads, no account required, and no limits on how many passwords you generate.
