How to Generate Secure Passwords Online
A step-by-step walkthrough of generating, evaluating, and storing strong passwords using nTropi.
What Makes a Password Secure?
Two factors dominate: length and randomness. A 16-character truly random password from a 94-character set has ~105 bits of entropy. A 6-word passphrase from a 7776-word list has ~78 bits — shorter entropy, easier to remember.
Step 1: Set Your Requirements
Open /tools/password-generator. Configure:
- Length: 16+ characters for general use, 32+ for master passwords
- Character set: enable all four groups (upper, lower, digits, symbols) for maximum entropy
- Exclude ambiguous: check this to avoid
0/Oandl/1confusion when typing manually
Step 2: Generate and Evaluate
Click Generate. The strength meter will show entropy in bits and a strength label. Aim for Strong or Very Strong.
Step 3: Copy Immediately
Click the copy button. Do not manually type — transcription errors are common.
Step 4: Store It
Use a password manager (Bitwarden, 1Password, KeePass). Never store passwords in plaintext files, browser autofill notes, or spreadsheets.
