Password Generator Guide: How to Create Strong Random Passwords

A password generator creates a password automatically instead of requiring you to invent one yourself.

The MartTools Password Generator creates random passwords from the character types you select. You can control the password length and choose whether to include lowercase letters, uppercase letters, numbers and symbols.

The generator starts with the character types selected in the options. It then builds a character set from those choices and uses the browser's cryptographic random number generator to select characters.

The password length can be adjusted from 4 to 64 characters. The default length is 16 characters with lowercase letters, uppercase letters, numbers and symbols enabled.

Password length is one of the main options in the generator. MartTools lets you choose a length between 4 and 64 characters.

Longer passwords provide more possible character combinations when the character set remains appropriately varied. The right length can depend on the requirements of the service where the password will be used.

The generator can include lowercase letters from a-z and uppercase letters from A-Z.

Using both character sets gives the generator more characters to choose from than using lowercase letters alone.

The Numbers option adds the digits 0 through 9 to the available character set.

Numbers can be combined with lowercase letters, uppercase letters and symbols when those options are enabled.

The Symbols option adds a set of punctuation and special characters to the password character set.

The generator's symbol set includes characters such as !, @, #, $, %, ^, &, *, parentheses and other supported symbols.

Some characters can be visually similar, especially when a password is displayed in a particular font. The MartTools generator provides an option to exclude the ambiguous characters Il1O0o.

Enable Exclude ambiguous when you want generated passwords to avoid those characters.

Open the Password Generator and choose the desired length and character options.

The generator automatically creates a password when the options change. You can also use the generate button to create another password using the current settings.

If you need to use the generated password elsewhere, the copy button places it on the clipboard.

The MartTools Password Generator displays a strength indicator for the generated password. The indicator can show Weak, Fair, Strong or Very Strong.

The displayed strength is based on characteristics including password length, whether lowercase and uppercase letters are present, whether numbers are included, whether symbols are included and whether the password reaches longer length thresholds.

The strength indicator is a quick guide provided by the tool. It is not a guarantee of how a particular website or security system will evaluate the password.

A generated password does not require you to come up with a predictable combination of words or characters yourself.

Random generation can be useful when you need a different password for a new account or service and want the password to be generated from a configurable character set.

Use a different password for each important account rather than relying on one password across multiple services.

When a website or service has its own password requirements, configure the generator to match those requirements before copying the result.

Avoid sharing generated passwords unnecessarily, and use appropriate account security features offered by the service.

Creating a password manually requires you to select the characters yourself. A generator automates that selection and can produce a new result whenever needed.

The MartTools generator also lets you control the length and character categories instead of producing every password using exactly the same settings.
