Generate 16-Character Password
16 characters is the sweet spot for security and memorability. Generate a cryptographically secure 16-character password with uppercase, lowercase, numbers, and symbols — no data sent to any server.
Your files are never sent to our serversHow it works
Our password generator uses your browser's crypto.getRandomValues() API, the same cryptographic function used by banks and governments. The password is generated locally and never transmitted, stored, or logged anywhere.
Step-by-step
- Click the button below to open the Password Generator
- Set length to 16 characters (or adjust as needed)
- Choose character types: uppercase, lowercase, numbers, symbols
- Click 'Generate' to create your password
- Copy the password to your clipboard
- Store it in your password manager (Never write it down)
Supported formats
Generates ASCII passwords compatible with all websites, apps, and systems. Supports lengths from 8 to 128 characters. Optional exclusion of ambiguous characters (0, O, l, 1).
Is it safe?
Extremely safe. The password exists only in your browser's memory for the few seconds you need it. It is never sent to any server, not even ours. For maximum security, use a password manager to store generated passwords.

Is a 16-character password secure enough?
Yes. A 16-character password with mixed characters would take billions of years to crack via brute force.
Can I use this password for my bank?
Yes, but we recommend using a unique password for each account. Consider a password manager for this.
Is this truly random?
Yes. We use crypto.getRandomValues(), which provides cryptographically secure random numbers from your device's hardware.
