Our Random Password Generator creates strong, secure passwords instantly and entirely in your browser. You decide the length, the character sets, and how many passwords you need (1 to 20), and the tool guarantees at least one character from every set you select. Because everything happens on your device, your passwords are never sent to, or saved on, any server. This makes your password visible and accessible only to you, and eliminates any risk of them ending up with the wrong persons.

Set the length: Drag the "Password Length" slider anywhere from 4 to 64 characters. The chosen length is shown next to the label.

Choose the character sets: Tick or untick Uppercase, Lowercase, Numbers and Symbols. You need at least one set to generate a password. If a set is selected, the generated password is guaranteed to contain at least one character from it.

Exclude ambiguous characters (optional): Turn on "Exclude ambiguous characters" to keep out the easily confused characters 0, O, o, 1, l and I, which helps when passwords are read aloud or typed by hand.

Set the number of passwords: Choose between 1 and 20. Leave it at 1 for a single password, or increase it to generate several unique passwords at once (one per line).

Click "Generate": Press the "Generate" button to create your password or passwords.

Copy or download: Use "Copy" to copy the output to your clipboard, or "Download" to save it as a text file.

Read the strength: When a single password is generated, the tool also shows its strength rating and the estimated brute-force attempts needed to crack it.

Password Length: A longer password is harder to crack than a shorter one, even with a bigger character set. For example, an 8-character password using only numbers has 10^8 (100 million) combinations and is rated Weak, while a 12-character password using all four sets has about 2.5 x 10^23 combinations and is rated Strong.

Character Sets: You can build your pool from uppercase letters, lowercase letters, numbers and symbols, alone or in any combination. The password always includes at least one character from each selected set. For example, with only Lowercase and Numbers selected, every generated password contains both a letter and a digit.

Exclude Ambiguous Characters: With this option off you might get a password such as A1O0lI2x. Turning it on removes 0, O, o, 1, l and I from the pool, so the same settings could produce AaB4C9x7 instead - characters that cannot be misread.

Number of Passwords: Set this to 1 for a single password, or enter a number up to 20 to generate a batch of unique passwords at once. Each one is independent, so no two are ever the same. For example, setting it to 5 produces five separate passwords, one per line, ready to paste into your records.

Strength and Crack Estimate: For a single password, the tool calculates its entropy as length x log2(pool size) and rates it Weak, Fair, Good, Strong or Excellent, with a strength score from 1 to 100 (the entropy in bits, capped at 100). It then shows the estimated number of attempts an offline brute-force attack would need, assuming a fast attacker trying 10 billion guesses per second. The default settings (8 characters, all four sets) come out around 52 bits of entropy - about 3.9 x 10^15 attempts, which is roughly 4.5 days at that speed.

Use the Random Password Generator whenever you need a fresh, secure password and do not want to invent one yourself. It is especially handy when:

Creating new accounts: sign up for a service with a long, random password instead of reusing an old one.

Refreshing old passwords: replace a weak or reused password with a strong one in a few clicks.

Generating test data: developers often need random strings for fixtures, dummy user data, or seeded database records.

Creating secrets and keys: quickly produce random strings for API secrets, tokens, or local configuration files.

Sharing Wi-Fi or guest access: generate a password that nobody can guess and that is easy to hand over in writing.

For the best security, store your generated passwords in a trusted password manager so you never have to remember or retype them.

FAQ 1: Is this password generator free to use?
Answer: Yes, it is 100% free and requires no sign-up or login.

FAQ 2: Are my generated passwords stored or sent anywhere?
Answer: No. The passwords are generated on your own device using cryptographically secure randomness, and nothing is transmitted to, or stored on, any server. You can clear the output any time.

FAQ 3: How is the password strength calculated?
Answer: The strength is based on entropy, which is the password length multiplied by the logarithm (base 2) of the size of the character pool you selected. Higher entropy means more possible combinations and therefore a stronger password.

FAQ 4: What does "Exclude ambiguous characters" do?
Answer: It removes the easily confused characters 0, O, o, 1, l and I from every selected set, so the generated password contains no characters that are difficult to tell apart when typed or read by hand.

FAQ 5: Can I generate more than one password at a time?
Answer: Yes. Set the "Number of Passwords" value between 1 and 20. Each generated password is independent and unique, and the output lists one password per line.

FAQ 6: How should I keep the generated passwords safe?
Answer: Save them in a trusted password manager so they are encrypted and available across your devices. Never share a password, and use a different password for every account.
