Generate a strong, random password instantly. Choose a length from 6 to 64 characters and customize the use of uppercase letters, lowercase letters, numbers, and symbols. Every password is generated privately in your browser.
Generated locally in your browser. Your password is never sent to our server.
Generate a Strong Random Password Online
Toolisto is a free online password generator for creating unique passwords in seconds. You can customize the password length, select the character types you need, exclude similar-looking characters, and copy the result with one click.
No registration or personal information is required. The generator works directly in your browser, so the generated password is not sent to the Toolisto server.
Use the generator when creating or updating passwords for email, social media, online stores, work accounts, Wi-Fi networks, cloud services, applications, and other protected resources.
How to Create a Secure Password
Creating a random password with Toolisto takes only a few steps:
- Choose the password length. The generator supports passwords from 6 to 64 characters.
- Select uppercase and lowercase letters, numbers, and symbols.
- Enable “Exclude similar characters” if you want to avoid characters such as
O,0,I,l, and1. - Click “Generate new password” to create another random combination.
- Click “Copy” and save the password in a trusted password manager.
For most online accounts, start with at least 16 characters. If a website has specific password requirements, adjust the length and character settings before generating a new password.
What Is a Random Password Generator?
A random password generator is a tool that creates passwords from unpredictable combinations of characters. Unlike passwords invented by people, generated passwords do not normally contain names, birthdays, keyboard patterns, common words, or other information that can be guessed.
A strong password generator also lets you control the password’s length and available character set. This makes it possible to meet the requirements of different websites while preserving randomness.
What Makes a Password Strong?
A strong password is long, random, and unique. These three properties are more important than making a password look complicated.
- Long: Additional characters increase the number of possible combinations.
- Random: The password should not contain predictable words, dates, names, or patterns.
- Unique: Every account should use a different password.
- Safely stored: A strong password should be kept in a trusted password manager.
- Protected by MFA: Multi-factor authentication provides an additional layer of security if a password is exposed.
Current NIST Digital Identity Guidelines identify password length as a primary security factor and require at least 15 characters when a password is the only authentication factor. Toolisto therefore uses 16 characters as its default setting.
Why Should Every Account Have a Unique Password?
Using the same password for multiple accounts creates a serious security risk. If one website experiences a data breach, attackers may try the exposed email and password on other services. This type of automated attack is known as credential stuffing.
A unique password limits the damage to one account. Generate a different password for every email address, social network, store, financial service, work platform, and administrator account.
Because remembering dozens of random passwords is difficult, store them in a password manager rather than in an unprotected document, email, or note.
How Toolisto Generates Passwords Privately
Toolisto generates passwords locally on your device. The password generator uses the browser’s Web Crypto API instead of the less secure Math.random() function.
During generation, the tool:
- creates cryptographically secure random values in your browser;
- builds a character pool from your selected options;
- includes characters from every selected category;
- securely shuffles the generated characters;
- displays the result without submitting it to the server.
The Toolisto generator does not save generated passwords in a database or account. If the browser does not support secure random generation, the tool stops instead of falling back to a weaker method.
The strength indicator provides a useful estimate based on password length and the size of the selected character pool. It should not be treated as a guarantee that an account can never be compromised.
Recommended Password Length
For most accounts, a randomly generated password of 16 or more characters is a practical starting point. Longer passwords provide an additional security margin when the website supports them.
| Use case | Suggested starting length | Additional protection |
|---|---|---|
| General online account | 16+ characters | Use a unique password |
| Email or cloud storage | 20+ characters | Enable MFA or a passkey |
| Administrator account | 20–32 characters | Use MFA and restrict access |
| Wi-Fi network | 20+ characters | Use WPA2 or WPA3 |
| Password manager master password | Long passphrase | Never reuse it elsewhere |
Always follow the requirements of the service where the password will be used. Some older websites may limit password length or reject particular symbols.
Password Safety Tips
Generating a strong password is only the first step. To protect your accounts:
- use a separate password for every account;
- save passwords in a reputable password manager;
- enable multi-factor authentication whenever possible;
- use passkeys when a trusted service supports them;
- never send important passwords through unencrypted messages;
- do not store passwords in plain-text spreadsheets or documents;
- replace a password immediately if it may have been exposed;
- keep account recovery information up to date.
The US Cybersecurity and Infrastructure Security Agency also recommends using passwords that are long, random, and unique, together with a password manager. See the CISA password security guidance.
Frequently Asked Questions
Yes. Toolisto is a free password generator that works without registration, subscriptions, or usage limits.
No. The password is generated locally in your browser. The Toolisto generator does not send the generated value to its server or save it in a database.
An online password generator can be safe when it uses a cryptographically secure source of randomness and processes the result locally. Toolisto uses the browser’s Web Crypto API and does not use a server request to generate the password.
Use at least 15 characters for a password-only account and preferably 16 or more when the service allows it. Sensitive accounts may benefit from passwords of 20 characters or longer, together with multi-factor authentication.
A unique, genuinely random 16-character password is a strong choice for most online accounts. Its security still depends on how it is stored, whether it is reused, and whether the account uses additional protection such as MFA.
Numbers and symbols increase the available character pool, but length, randomness, and uniqueness remain essential. If a website permits all character types, enabling uppercase letters, lowercase letters, numbers, and symbols is a convenient option.
Characters such as O, 0, I, l, and 1 can be difficult to distinguish when a password is read or typed manually. Excluding them reduces transcription errors. It slightly decreases the character pool, so use a longer password if needed.
Yes. You can generate a long random password for a home or office Wi-Fi network. A length of at least 20 characters is a useful starting point, provided the router and connected devices accept the selected symbols.
No. Generate a different password for every account. Reusing a password allows a breach involving one service to threaten your other accounts.
No password comes with an absolute guarantee. A long and random password greatly reduces guessing and brute-force risks, but account security also depends on the website, device security, safe storage, phishing protection, and multi-factor authentication.
