Password Generator

Why random passwords matter: Most data breaches occur because of weak or reused passwords. A randomly generated password with sufficient length and character variety is practically impossible to guess or crack through brute force. Never use personal information (birthdays, names, pet names) in passwords.

Password entropy explained: Entropy measures password randomness in bits. A password with 40 bits of entropy has 2^40 (about 1 trillion) possible combinations. For good security, aim for at least 60 bits. Each additional character type (uppercase, numbers, symbols) and length increase entropy significantly.

Use a password manager: With unique passwords for every account, you need a reliable way to store them. Password managers like Bitwarden (free, open-source), 1Password, or KeePass encrypt and store all your passwords securely. You only need to remember one master password.

Enable two-factor authentication (2FA): Even the strongest password can be compromised through phishing or data breaches. Always enable 2FA where available. Hardware keys (YubiKey) or authenticator apps (Google Authenticator, Authy) are more secure than SMS codes.

How long to crack? A 8-character password with only lowercase letters can be cracked in seconds. Add uppercase, numbers, and symbols, and it takes hours. At 12 characters with all types, it takes centuries. At 16+ characters, it is practically uncrackable with current technology.
