Enter your desired password length and choose which character types to include — uppercase letters, lowercase letters, numbers, and symbols — then get a strong, random password generated on the spot. Copy it with one click and use it to secure any account.

The generator builds a character pool based on the options you select — uppercase letters, lowercase letters, numbers, and symbols. It then randomly picks characters from that pool one at a time until your chosen password length is reached, producing a unique, unpredictable password every time you click Generate.
A strong password is long (at least 12 characters), uses a mix of uppercase and lowercase letters, numbers, and special symbols, and avoids dictionary words or predictable patterns. The more character types and the greater the length, the larger the possible combinations — making brute-force attacks exponentially harder.
A truly random, long password is extremely difficult to crack. A 16-character password using all character types has trillions of possible combinations. While nothing is 100% unbreakable, a high-entropy password generated by this tool would take centuries to crack using current hardware.
Security experts generally recommend a minimum of 12 characters, with 16 or more being ideal for sensitive accounts. Longer passwords dramatically increase entropy (randomness), making them far more resistant to brute-force and dictionary attacks.
Yes — absolutely. Reusing passwords means that if one account is breached, attackers can use the same credentials to access your other accounts. A password manager can store unique passwords for every site so you only need to remember one master password.
Weak passwords include dictionary words (password, sunshine), sequential strings (123456, abcdef), personal information (your name, birthday, or pet's name), and short passwords under 8 characters. These can be cracked in seconds using automated tools.
Yes. All password generation happens entirely in your browser using JavaScript — no password is ever transmitted to or stored on any server. Each password is generated fresh on your device, meaning it is private and never logged.
Entropy measures the unpredictability of a password in bits. Higher entropy means more possible combinations and a harder password to guess. It is calculated as: length × log₂(pool size). A password with 80+ bits of entropy is considered very strong against modern attacks.
