Password Generator

Password generator for secure random passwords with custom length, character sets, confusing-character exclusions, and zxcvbn-based strength analysis for accounts, admin panels, Wi-Fi credentials, and rotation policies.

Password Length

Password Options

Quick Templates

High Security

Include uppercase letters (A–Z)

Include lowercase letters (a–z)

Include numbers (0–9)

Include symbols (!@#$%^&*)

Exclude similar characters (il1Lo0O)

Exclude ambiguous characters ({}[]()'"/\)
Password Generator

Quick Start

1
Set length (recommended 12–16)
2
Select character types (uppercase/lowercase/digits/symbols)
3
Or choose a template (Basic/Strong/High Security/Readable)
4
Click Generate, then copy and save (refresh clears)

Common Scenarios

Sign‑up/reset

generate unique strong passwords per site to reduce stuffing risk

Admin/production

prefer length ≥16, include symbols, exclude confusables for better typing

VPN/remote access

use longer passwords (20+), store in a password manager

Router/Wi‑Fi

use the Readable template for easier input and sharing

Temporary access

one‑time password; rotate or disable after use

Extended workflow

secure password generator, password strength checker, and password creator can be handled in the same review flow, so you can verify results before copying or exporting.

Strength Assessment & Principles

Uses zxcvbn: entropy analysis, dictionary checks, pattern recognition, crack‑time estimate
Scoring: 0–1 weak, 2 fair, 3 strong, 4 very strong
Crack time: estimated under common attack models; actual depends on attacker and hardware
Smart detection: flags common passwords, repeats, dictionary‑like patterns

Usage Advice

✅ Recommended: 12+ characters with all 4 types; avoid common passwords and patterns
❌ Avoid: personal info (birthdays, names, emails), common passwords, keyboard sequences (qwe, 123, abc)
Check crack time/strength before adopting
When typing by hand, prefer “Readable Password”
Use different passwords per site to prevent credential stuffing
Use a password manager: generate and store complex passwords securely

Limitations & Compatibility

Batch limit: up to 5 per run
Length: 8–64; if N types selected, length must be ≥ N
Excluding similar/ambiguous characters reduces the pool and may affect variety
Guess rate assumptions: online (rate‑limited) vs offline (high‑throughput) differ greatly; strength estimates depend on this — defer to the actual environment

Privacy & Security

All processing happens locally in your browser. You can regenerate, replace, and clear the current result at any time.
Copy and store immediately after generation; consider a password manager
