Frequently Asked Questions
What makes a password random and secure?
A random and secure password is long and uses a mix of different character types (uppercase, lowercase, numbers, and symbols). It uses cryptographic random number generators (unlike basic math random functions) making it virtually impossible to guess or brute-force quickly.
Is my generated password saved anywhere?
No. Passwords are generated entirely locally on your device within your browser. They are never sent over the internet or saved on our servers. The history feature only saves them in your device's local storage temporary memory.
How long should a strong password be?
For most standard accounts, a minimum of 16 characters is highly recommended by security experts. For critical accounts (like password managers, banking, or crypto wallets), 20 to 32 characters or more is optimal.
Why exclude ambiguous characters?
Ambiguous characters (like uppercase 'I', lowercase 'l', number '1', or letter 'O' and number '0') look very similar in certain fonts. Excluding them makes the password much easier to read and type manually without errors.
What does Entropy mean?
Password entropy is a measurement of how unpredictable a password is, calculated in bits. The higher the entropy, the harder it is for algorithms or attackers to guess the password. A score above 80 bits is generally considered very strong.
