What is a Password Generator?

The Password Generator instantly creates a random string of characters you can use as a password, based on a length you choose. With data breaches at Indian banks, e-commerce platforms, and government portals making headlines almost every year — CERT-In logs well over a lakh cyber-security incidents annually — using a unique, unpredictable password for every account, rather than a name, birthdate, or "password123", is one of the simplest ways to cut your risk of getting hacked.

How It Works

You choose a desired length (the tool defaults to 12 characters if you leave the field blank or enter 0). The generator builds a pool of allowed characters, then, for every single position in the password, picks one character from that pool completely at random using the browser's built-in random-number function — so no two runs produce the same password, and each character is chosen independently of the ones before it.

  • By default the tool draws from uppercase (A-Z), lowercase (a-z), and digits (0-9) — a pool of 62 possible characters per position. Tick the "Symbols" box to also include punctuation characters, or untick any box to exclude that character type entirely.
  • At least one character type must stay checked — with all four ticked, each of the 12 default positions is chosen independently from a 94-character pool, giving a 12-character password roughly 94¹² possible combinations.

Worked Example

With the default length of 12 and uppercase, lowercase, and digits all ticked, the generator might output something like K3jQd271mFa9. Tick the Symbols box as well and you might instead get something like h2#vQ0z!a8&1r, drawn from all four character types at once.

How to Use This Tool

  1. Enter your desired Password Length (defaults to 12 if left empty).
  2. Click Calculate to generate a fresh random password.
  3. Copy the result into a password manager rather than reusing it or storing it in a plain-text file or notes app.

Things to Know

💡 Tip: Length matters more than complexity. A 16–20 character password is far harder to brute-force than an 8-character one, even if the shorter one mixes cases and symbols. Where a website or app allows it, choose the maximum length permitted, and never reuse the same password across your net banking, UPI apps, and personal email.
