Strong password generator
Online strong password generator
The strong password generator creates cryptographically secure combinations of uppercase and lowercase letters, numbers, and special characters. A pool of 94 possible characters ensures maximum entropy. Password length — from 4 to 100 characters.
A strong password is the recommended standard for email, social networks, cloud services, and any accounts requiring reliable protection. Each password is generated using Crypto.getRandomValues().
Generation is performed entirely on the client side. No characters are transmitted to the server. A zero-knowledge architecture guarantees that your password exists only in your device's RAM.
Features
- Letters A–Z, a–z, numbers 0–9 and special characters — 94 characters in the pool
- Length from 4 to 100 characters, up to 100 variants at once
- Cryptographically secure Crypto.getRandomValues() API — true randomness
- Zero-knowledge: the password never leaves the device
- Instant copying — clickable chips
- Free, no registration, no limits
How it works
Create a strong password in four steps
An intuitive interface lets you get results in seconds.
01
Choose a category
Switch to the desired mode on the toolbar. Each mode has its own set of settings.
02
Configure parameters
Specify the number of variants and additional options. The tool adapts to your requirements.
03
Run generation
Press the start button. All computations are performed locally on your device.
04
Copy the result
The result is displayed immediately. You can copy it with one click or generate a new one.
Password types
When to choose a strong password
Strong passwords are used everywhere maximum account protection is required.
Your mailbox is the center of your digital identity. A strong password protects access to recovering other passwords.
Cloud services
Google, Dropbox, iCloud store your files and data. A reliable password is the first line of defense against leaks.
Corporate systems
CRM, ERP, admin panels require maximum security. A strong password is the security standard.
Social networks
Facebook, Instagram, TikTok — a hacked account can cost you your reputation. Protect yourself with a strong password.
Benefits
Why a strong password is the security standard
94^16 combinations — billions of years of brute force on a GPU cluster.
Measurable entropy
16 characters from a pool of 94 — 94^16 combinations, ~105 bits of entropy. Each additional character exponentially increases security.
Zero-knowledge architecture
The server never receives or stores passwords. Generation happens in the browser. Can be used even without internet.
Flexible length
From 4 to 100 characters. 16 characters is enough for most accounts. For corporate systems — 20+.
Easy copying
Choose the output format: new line, comma, or tab for importing into a password manager.
Frequently asked questions
About strong passwords
How long should a strong password be?
At least 16 characters. 20+ characters is recommended for corporate systems and administrative access. Each additional character exponentially increases the difficulty of cracking.
How is a strong password different from a random one?
Strong mode guarantees characters from all classes (letters, numbers, special characters). Random mode simply picks from the available pool, which can yield even higher entropy.
How secure is a 16-character strong password?
A 16-character password with numbers, letters, and special characters yields 94^16 combinations. A cluster of 1000 GPUs would take billions of years to brute force such a space.
How do I remember a strong password?
Use a password manager — Bitwarden, KeePass, or 1Password. They securely store all passwords, and you only need to remember one master password.
