Why use Zyrro's Password Generator?
One click creates a strong, random password using your browser's built-in cryptographic random generator — the same class of randomness operating systems rely on for security. Choose a length from 8 to 64 characters and mix uppercase, lowercase, numbers, and symbols to match any site's password rules.
Every password is generated locally on your device. Nothing is sent to a server, stored, or logged — after you copy it, it's gone from this page. The live strength meter shows an entropy estimate in bits, so you can see exactly how hard your password would be to crack.
- Length slider: 8–64 characters to fit any requirement
- Character sets: uppercase, lowercase, numbers, and symbols — mix or match
- Exclude ambiguous: removes lookalikes like I, l, 1, O, and 0
- Strength meter: live rating from Weak to Very Strong with an entropy (bits) readout
- Memorable passphrase mode: 3–8 random words joined with your choice of separator, optional capitalization and a random number — easy to remember, hard to crack
- Pronounceable mode: easy-to-read consonant–vowel syllables with optional mixed case and a number — handy when you must type or say a password
- One-click copy: copy the password to your clipboard instantly
Frequently asked questions
Are my generated passwords stored or sent anywhere?
No. Passwords are created inside your browser using the Web Crypto API and never leave your device. This page has no accounts, no history, and no server receiving your passwords — once you copy one, it exists only where you save it.
How long should my password be?
For important accounts like email, banking, and social media, use at least 16 characters with all four character types — that's the setting this tool starts with. Watch the strength meter: aim for "Strong" (80+ bits of entropy) or better.
What do the strength meter and "bits of entropy" mean?
Entropy measures unpredictability — how many guesses an attacker would need in the worst case. A 16-character password drawn from all character types lands around 100+ bits, an astronomically large search space. More characters and more character types both raise the number.
What does "exclude ambiguous characters" do?
It removes characters that look alike — capital I, lowercase l, the digit 1, capital O, and zero — so passwords are easier to read and type correctly when you copy them from a note or a password manager.
Can I reuse a password across sites?
No — reuse is one of the most common ways accounts get compromised. If one site's database leaks, every account sharing that password is exposed. Generate a unique password for each site and store them in a reputable password manager.
What is a passphrase, and is it safer than a random password?
A passphrase joins several random words together, like "Coral-Dancer-Fig7". It is easier to remember than a jumble of symbols, and its security comes from the number of words: with 256 possible words per position, each word adds 8 bits of entropy. A 5-word passphrase gives about 40 bits — fine for low-risk logins — while 7–8 words approaches the strength of a 16-character random password. Use the Random mode for your most important accounts.
What are pronounceable passwords good for?
Pronounceable passwords are built from consonant–vowel syllables (for example "va-tie-pae"), so they are easy to read out loud, dictate over the phone, or type from memory. They trade some strength for usability — the strength meter shows the honest entropy estimate, so you can decide when convenience is worth it. Turn on mixed case and add a number to raise the strength.
