Frequently Asked Questions
How secure are the passwords generated by this tool?
The passwords generated by this tool use cryptographically secure random number generation and can be extremely secure when proper options are selected. A password with 16+ characters that includes a mix of uppercase, lowercase, numbers, and symbols can take centuries to crack using current technology. The strength indicator provides a visual guide to how secure your generated password is.
Why should I use a random password generator?
Human-created passwords are often predictable and follow patterns that can be exploited by attackers. We tend to use personal information, dictionary words with simple substitutions, or reuse passwords across sites. A random password generator creates truly unpredictable combinations that are much harder to crack through brute force, dictionary attacks, or social engineering.
How long should my password be?
For most standard accounts, a minimum of 12-14 characters is recommended. For sensitive accounts like banking or email, aim for 16-20 characters or more. Longer passwords are exponentially more difficult to crack. Our generator allows up to 64 characters for maximum security.
What's the difference between 'exclude similar characters' and 'exclude ambiguous characters'?
The 'exclude similar characters' option removes characters that look alike and can be confused when typing, such as 'i', 'l', '1', 'L', 'o', '0', and 'O'. The 'exclude ambiguous characters' option removes symbols that might be problematic in some contexts or hard to see, like brackets, slashes, and quotes. These options make passwords easier to read and type but slightly reduce the character pool.
Is it safe to save passwords in this tool?
Passwords saved in this tool are stored only in your browser's local storage and never transmitted to our servers. They remain on your device only. However, for maximum security, we recommend using a dedicated password manager like LastPass, 1Password, or Bitwarden for long-term password storage, as they offer encrypted vaults and additional security features.
How often should I change my passwords?
Current security best practices suggest changing passwords for critical accounts every 3-6 months, or immediately if there's any suspicion of a breach. However, using unique, strong passwords for each account and enabling two-factor authentication where available is more important than frequent password changes.
