When you sign up or log in from a new device, Desktop sends a one-time code to your email. This confirms it's really you.
How it works:
Enter your email and password
Desktop sends a verification code to your inbox
Enter the code within the time limit
You're logged in
Didn't receive the code?
Check your spam folder. If it's still not there, request a new code.
This step keeps your account and your service's compliance data secure.
