Using the module

To generate a password, we have to import 'generate-password' module using the require function and then call generate method by passing the length of the password, character set, etc. It will generate the password according to the values passed to the generate method. Below is the code to import the module into our application.

const generator = require('generate-password');

Example : Implementation to Generate Random and Unique Password in Node.js.

// index.js

const generator = require('generate-password');

const passcode = generator.generate({
    length: 10,
    numbers: true
});

console.log(passcode);

Output:

Example 2: Implementation to Generate Random and Unique Password in Node.js using another example.

// index.js

const generator = require('generate-password');

const password = generator.generate({
    length: 8,
    numbers: true,
    symbols: true,
    uppercase: false,
    excludeSimilarCharacters: true,
    strict: true,

});

console.log(password);

Output:

Conclusion

In conclusion, the "generate-password" NPM module provides developers with a valuable resource for generating secure passwords that meet specific criteria, such as length and character types. This module is user-friendly, highly configurable, and offers a range of options to create robust passwords. However, it's important to note that while this tool can assist with password generation, it's the user's responsibility to implement proper password management and security practices.
