Generate secure random passwords
12 or more characters recommended. Longer passwords are more secure.
Use different passwords for each website.
Password Generator is a secure tool that creates cryptographically random passwords directly in your browser. It supports multiple generation modes including fully random, pronounceable, passphrase, and PIN code generation. The tool displays password strength metrics including entropy bits and estimated cracking time, helping you understand exactly how secure your password is. You can customize character sets, exclude ambiguous characters, and bulk generate up to 100 passwords at once for team or multi-account use.
Set password length
Set your desired password length using the slider or input field. For security purposes, we recommend at least 12 characters.
Select character options
Select the character type you want to include: uppercase letters, lowercase letters, numbers, and special characters. You can also set the option to exclude ambiguous characters.
Select a Generation Mode (Optional)
In addition to the default random, you can select special modes such as PIN code, easy-to-pronounce password, and passphrase.
Check and copy strength
Check the entropy and expected cracking time of the generated password, and copy it to the clipboard with the copy button.
Generate in Bulk (Optional)
If you need passwords for multiple accounts, generate up to 100 at once and download them as a TXT file.
Yes, it is unpredictable because it uses Web Crypto API's cryptographically secure random number generator (CSPRNG). The creation process takes place only within the browser and is not transmitted to the server, so there is no risk of external leakage.
Entropy measures a password's randomness in bits. Higher entropy increases the number of possible combinations exponentially, making brute-force attacks harder. In general, 60 bits or more is secure, and 80 bits or more is very strong.
This is an option to exclude characters that are difficult to distinguish visually, such as 0 (number) and O (uppercase letter), 1 (number) and l (lowercase letter), and I (uppercase letter). This is useful when you need to transcribe your password by hand or deliver it over the phone.
A passphrase is a long password made up of several words, such as correct-horse-battery-staple. It has the advantage of being easy to remember and having high entropy due to its long length. A passphrase of 20 characters or more can be more secure than a complex 12-character password.
According to the latest security guidelines (NIST SP 800-63B), it is recommended to change passwords immediately when a breach is identified rather than on a regular basis. Use a sufficiently strong password, and use a password manager with two-factor authentication (2FA).
