Postgres Password Generator

The Postgres Password Generator Tool creates secure hashes that match PostgreSQL’s md5 authentication format. Just input a password and username (like mysecret:postgres) and this tool outputs the correct md5-formatted password hash used in CREATE USER or ALTER ROLE statements.

Enter password and username separated by a colon, or import from file below.
No file chosen
Supported file types: .txt, .csv, .json, .log, .md, .yaml, .yml
Total characters: 0

How to Use:

  1. Enter the password and username separated by a colon.
  2. Or upload a file in the format password:username.
  3. The hash appears live in the output.
  4. Click Copy Output or Export to File to save it.
  5. Use Clear All to reset the form.

What Postgres Password Generator Tool can do:

It applies md5(MD5(password + username)), resulting in the same format PostgreSQL uses internally for authentication. The output is perfect for populating system catalogs or SQL script testing.

Example:

Input:

secret123:postgres

Output:

md5cfd520dd98914a4e5f6f42af68073e47

Common Use Cases:

  • Generating hashed credentials for PostgreSQL roles
  • Preparing secure SQL scripts with hashed passwords
  • Teaching PostgreSQL authentication formats
  • Comparing client/server hash generation output

Everything is processed locally in your browser no uploads, no logging, 100% client-side and private. Let me know if you want SCRAM-SHA-256 support added next.

Useful Tools & Suggestions:

If you’re securing more than one database type, the MySQL Password Generator gives you strong credentials tailored for that platform too. And when you want added control over complexity or formatting, the Strong Password Generator gives you custom options across any system.
