Secure Password Generator

Generate strong random passwords locally with configurable length, character groups, and batch output.

Runs locally in your browser. No account required.

Practical usage guide

What this tool does

Password Generator creates one or more random passwords locally with crypto.getRandomValues, the browser cryptographic random source. You choose the length, count, and character groups: lowercase letters, uppercase letters, digits, and symbols. No seed, master password, or generated value is sent to ToolFable by the generator.

For every enabled character group, each generated password contains at least one character from that group, with the remaining positions drawn from the combined selected alphabet. Excluding ambiguous characters can make manual reading easier, but it also reduces the alphabet and does not replace sufficient length, unique passwords, secure storage, or multi-factor authentication.

Quick start

Select the allowed character groups

Enable the groups accepted by the destination service. At least one group must remain selected, and the requested length must be large enough to include one character from every enabled group.

Choose length and count deliberately

Prefer a long unique password for a real account and generate only as many values as you need. Larger batches increase the amount of sensitive text visible on screen and available to copy accidentally.

Exclude ambiguous characters only when useful

The option can remove look-alike characters that are easy to confuse during manual transcription. Leave the full alphabet available when passwords will be copied and stored electronically and the service accepts it.

Store the selected password immediately

Move the chosen value into a trusted password manager or secret store, confirm that it was saved correctly, and clear exposed clipboard history where the operating environment permits.

Common use cases

Create a unique account password

Generate a fresh value for one website or application instead of reusing a memorable password across services.

Prepare a service or device credential

Create a local random password for a database user, development appliance, temporary environment, or other system that accepts the selected character groups.

Populate non-production test accounts

Generate several independent passwords for local fixtures or QA accounts without inventing predictable patterns such as Password1 or sequential suffixes.

Replace an exposed or reused password

Create a new unrelated value during credential rotation, then update the password manager and revoke old sessions according to the service recovery process.

Limitations and important notes

Random generation cannot secure a compromised device

Malware, a hostile browser extension, screen capture, key logging, injected page code, or an untrusted operating system can observe generated values. Use a clean, updated device for consequential credentials.

The clipboard can leak secrets

Copied passwords may remain in clipboard managers, synchronization services, remote desktop sessions, screenshots, crash reports, or another application. Paste only into the intended destination and clear history when appropriate.

Destination password rules still apply

A service may reject certain symbols, impose a maximum length, normalize Unicode, or require specific groups. Review the target rules and avoid weakening the password more than compatibility requires.

A strong password is one control

Generation does not configure multi-factor authentication, protect password-manager recovery, detect phishing, rotate leaked credentials, or verify that a service stores passwords safely.

Examples

Generate five strong passwords

Create 20-character passwords using every character group while excluding lookalikes.

Frequently asked questions

Where are passwords generated?

Passwords are generated in your browser with crypto.getRandomValues. ToolFable does not send or store the generated values.

Does each password contain every selected character type?

Yes. Each generated password includes at least one character from every enabled group, then all characters are securely shuffled.

Is a generated password automatically safe to use?

Strong randomness helps, but device security, clipboard history, password reuse, phishing, and service-specific rules still matter. Store passwords in a trusted password manager.
