Mylanviewer 4.14.1 Portable May 2026

Client-side tool to generate/verify password hashes with realistic parameters. Helpful for debugging integrations and understanding how salts, memory, and iterations affect cost. Runs locally—no passwords leave your browser.

Your data security is our top priority. All hashing and verification happen in this browser. This tool does not store or send your password nor hashes outside of the browser. See source code in: https://github.com/authgear/authgear-widget-password-hash

He clicked Impersonate Session .

A live view of Whitaker’s desktop appeared. Outlook was open. An unsent email sat in the draft folder, addressed to the firm’s entire client list. The subject line read: "We are dissolving effective immediately. Here is where your money went."

For a long moment, he considered his options. Delete the software. Walk out. Never speak of it. But then he looked back at the screen—at the glowing amber dot next to WHITAKER-DESK , the managing partner’s own machine.

Next to an entry labeled BACKUP-ARCHIVE was an amber dot. He clicked it. A tooltip appeared: "Shadow session available. Credentials: cached."

How to use the Password Hash Generator

Step 1.

Enter a password

Open the Generate tab and type a demo password (avoid real credentials).

Step 2.

Select an algorithm

For new systems, Argon2id is generally recommended.

Step 3.

Set parameters:

Argon2id: Memory (MiB), Iterations (t), Parallelism (p).
‍bcrypt: Cost (2^cost rounds).
scrypt: N (power of two), r, p.
PBKDF2: Iterations and digest (SHA-256/512).

Step 4.

Generate Password Hash

Click Generate Password Hash. Copy the encoded string.

Step 5.

Verify Password Hash

Switch to Verify Password Hash to test a password + encoded hash pair.

Is it safe to use this with real passwords?

All hashing happens locally in your browser. For your own safety, avoid using production secrets in any online tool.

Which hashing function should I use?

For new systems, Argon2id is generally recommended. bcrypt and scrypt are widely deployed; PBKDF2 is a compatibility fallback. Always benchmark and choose parameters that meet your latency targets.
