Two-Factor Authentication

What is two-factor authentication?

Two-factor authentication (Two-Factor Authentication / 2FA) is a system that verifies your identity using two methods when you log in. In addition to normal "password authentication," performing one additional authentication increases account security.

Dive supports TOTP (Time-based One-Time Password). To use this feature, you use a common authentication app such as Google Authenticator orMicrosoft Authenticator.

At Dive, you can use two-factor authentication with confidence on all plans, including the Free plan.

Why is two-factor authentication necessary?

Password-only authentication has the following risks:

• Password leaks

• Use of easily guessed passwords

• Unauthorized login due to data breaches from other services

When you enable two-factor authentication, you can prevent unauthorized login even if your password is compromised.

How two-factor authentication works

When you log in, you authenticate using the following two elements combined:

1. Something you know

   • Password

2. Something you have / Information generated on the spot

   • Confirmation code displayed in a smartphone authentication app (Dive uses this method)

   • Confirmation code sent via SMS

   • Confirmation code sent via Email, etc.

Setup instructions

2. Click "Two-factor authentication settings"
   

3. A QR Code for setup will be displayed. Scan it with your authentication app, enter the one-time password, and click "Enable" to complete the setup.
