How to Fix Suspicious Login Attempt Error on Gmail in Windows 11: Step-by-Step Guide

Encountering a suspicious login attempt error on Gmail can be frustrating, especially when you are sure it was you trying to access your account. This error appears when Gmail detects a login from an unrecognized device or location, aiming to protect your account from unauthorized access.

Windows 11 users might see this alert while trying to sign in, and it can temporarily block access to your Gmail account. Fortunately, there are straightforward steps to resolve this issue and regain access safely.

This guide will walk you through the easiest and most effective ways to fix the suspicious login attempt error on Gmail while using Windows 11.

By following these instructions carefully, you can secure your account and prevent future interruptions.

Quick Note: What to Check Before Starting

  • Ensure your internet connection is stable: Unstable networks can trigger unusual login alerts.
  • Verify your device and location: Gmail flags logins from new devices or unfamiliar places.
  • Have your recovery options ready: Keep your phone number and backup email updated for verification.
  • Use a supported browser: Google Chrome, Microsoft Edge, or Firefox usually work best on Windows 11.

Step 1: Confirm the Login Attempt is Legitimate

First, check your email or phone for security alerts from Google. These notifications usually contain details about the suspicious login, such as the device type and location.

If you recognize this login attempt, you can safely proceed to unlock your account. If you don’t, immediately change your password to secure your account from potential unauthorized access.

Step 2: Verify Your Identity with Google

Google often asks for identity verification after detecting suspicious activity. Follow these simple steps:

  1. Go to the Google Account Recovery page.
  2. Enter your email address and follow the prompts.
  3. Google may ask to send a verification code to your recovery phone or email.
  4. Enter the received code to confirm your identity.

This step helps Google confirm that it’s really you trying to access the account, reducing the chance of unauthorized access.

Step 3: Review and Update Account Security Settings

Once logged in, review your security settings to prevent future suspicious login errors:

  • Change your password: Choose a strong, unique password. Avoid using common words or easily guessable information.
  • Enable Two-Factor Authentication (2FA): This adds an extra layer of security by requiring a code from your phone every time you log in.
  • Check Recent Security Events: Visit the Security Checkup page to see recent login activity and devices connected to your account.
  • Update Recovery Information: Make sure your phone number and backup email address are current.

Step 4: Use a Trusted Device and Network

Logging in from a trusted device and network reduces the chances of Gmail triggering suspicious login warnings. Follow these tips:

  • Use your personal computer or smartphone that you frequently use to access Gmail.
  • Avoid logging in from public Wi-Fi networks or shared devices.
  • If you must use a new device, try connecting through a VPN or your home network to match previous login locations.

Step 5: Clear Browser Cache and Cookies

Sometimes, stored cache and cookies can interfere with account verification. Clearing them can help:

  1. Open your browser (Chrome, Edge, or Firefox).
  2. Go to Settings > Privacy and Security > Clear browsing data.
  3. Select “Cookies and other site data” and “Cached images and files.”
  4. Click Clear data and restart the browser.

After clearing, try signing in again to see if the error persists.

Alternative Method: Use Google’s “Less Secure Apps” Setting (Not Recommended)

If you are using an older email client or app to access Gmail, Google may block sign-ins due to security restrictions. You can temporarily allow less secure apps by:

  1. Visiting the Less Secure Apps page.
  2. Turning on access for less secure apps.

Note: This reduces your account’s security and is not recommended for regular use. Instead, update your apps to ones that support OAuth 2.0 authentication.

FAQs

Why does Gmail show suspicious login attempts?

Gmail detects logins from new devices, locations, or IP addresses that differ from your usual activity to protect your account from unauthorized access.

Can I ignore suspicious login alerts if it was me?

It’s best not to ignore them. Confirm your identity to ensure your account remains secure and prevent Google from blocking access.

What if I can’t receive verification codes?

Check that your recovery phone number and email are correct. If you don’t have access to them, use Google’s account recovery options and answer security questions.

Will clearing cache delete my passwords?

Clearing cache and cookies removes stored website data but usually does not delete saved passwords unless you specifically choose to clear passwords.

Is two-factor authentication necessary?

While not mandatory, 2FA greatly enhances your account security by requiring a second verification step during login.

Using trusted devices and networks, clearing browser data, and enabling two-factor authentication can help prevent this error from recurring. If problems persist, Google’s official support resources are available to guide you further.
