Login Methods

Four ways to sign in — username and password, Google, QR code, and email one-time codes

In this guide

Password login and Email OTP both use your username — not your email address — as the identifier. Open the login page from Log In.

Username & Password

Use the Username & Password tab. Enter your username and password, agree to the Terms and Conditions if prompted, then click Log In. Optional Remember me for 30 days keeps you signed in longer on that device.

Login page Username and Password tab — Username & Password tab on the login page

Use your username only — email is not accepted here
After several failed attempts, you may be asked to complete a reCAPTCHA
Your account must be confirmed, and you must agree to the current Terms

Google Account

On the same Username & Password tab, click Continue with Google to sign in with a linked Google account.

Continue with Google button on the login page — Continue with Google below the password form

QR Code

Generate a personal QR code in Settings, then scan it on a shared device that has a camera. The login page shows a Using QR Code tab when a camera is available.

Settings QR Login section — Generate or manage your QR code in Settings

QR code view modal — View, download, or print your login QR code

Login page QR Code scan tab — Scan your BlitzGrok QR code on the login page

In Settings, open QR Login and generate (or view) your code
On the login page, open Using QR Code and hold the code up to the camera
Codes stay valid until you regenerate or revoke them — regenerating invalidates the previous code

Email OTP

Prefer a one-time code instead of your password? Open the Email OTP tab, enter your username, and click Request OTP. A 6-digit code is emailed to the address on your account and expires in 3 minutes.

Email OTP verify form with countdown — Enter the 6-digit code within 3 minutes

Enter your username (not email) to request a code
Type the plain 6-digit code from your email before it expires
Requesting a new code replaces any previous unused code
Same confirmation and Terms requirements apply as password login

For privacy, the site always shows a generic “If an account exists…” message after you request a code — it does not confirm whether the username is registered.
