Fake 'New Device Login' Alert

A 'new device signed in — was this you?' alert links to a fake login page designed to steal your password and one-time code.

Think a message like this reached you? You can check it right now.

What this scam is

You get an alert that a new device or unusual login was detected, urging you to click 'this wasn't me' to secure your account. The link opens a lookalike login page that captures your username, password, and any two-factor code you enter. The alarm is engineered so that fear makes you log in fast without checking the address.

What it usually looks like

  • A 'new sign-in detected' or 'was this you?' message.
  • A 'secure your account' or 'this wasn't me' link.
  • A login page that mimics your bank or provider.
  • A prompt to enter a one-time code.

Common warning signs

  • The link's web address is not the real provider.
  • You are rushed to log in to 'stop' access.
  • It asks for your password and 2FA code on the same page.
  • The alert arrives out of context.

Example wording scammers use

New device signed in to your account from a new location. If this wasn't you, secure your account: account-security-check.net
Suspicious login detected. Verify it's you within 15 minutes or your account will be locked.
