What Does Arlo Error 1005 Mean and How Do I Fix Login Authentication Failure?
- Password is incorrect due to typo or forgotten change
- Account was migrated from Netgear Arlo and password did not transfer
- Two-factor authentication code expired or phone clock is wrong
Problem Description
When trying to log into the Arlo app or my.arlo.com you see Error 1005 which means authentication failure. Your login credentials are being rejected even though you believe the email and password are correct. Error 1005 prevents you from accessing your entire Arlo system including all cameras, recordings, and settings. This error is commonly caused by incorrect credentials, account migration issues from the old Netgear Arlo system to the new Arlo system, two-factor authentication problems, or account security lockouts.
Symptoms
- Arlo app shows Error 1005 authentication failure on login
- Correct password is rejected at the login screen
- Error started after Arlo account migration from Netgear
- Two-factor authentication code is not being accepted
- Account was working then suddenly cannot log in
- Error appears on both app and my.arlo.com website
Recognize these? Here's what usually causes it.
Common Causes
- Password is incorrect due to typo or forgotten change
- Account was migrated from Netgear Arlo and password did not transfer
- Two-factor authentication code expired or phone clock is wrong
- Account locked after too many failed login attempts
- Arlo authentication servers temporarily experiencing issues
- Account compromised and password was changed by unauthorized user
Most fixes happen in the first 3 steps.
If your Arlo account was compromised change the password immediately and review all shared user access. Someone with access to your Arlo account can view your camera feeds, disable cameras, and access recorded video. Enable two-factor authentication immediately after regaining access.
Step-by-Step Solution
Reset Your Password
On the Arlo login screen tap Forgot Password. Enter the email address associated with your Arlo account. Check your email for the password reset link. Click the link and create a new strong password. Log into the Arlo app with the new password. This resolves the majority of error 1005 cases especially if you are unsure whether your password was changed at some point.
Check for Netgear Migration Issues
If you originally set up your Arlo system years ago when it was under Netgear your account may have been migrated to the new Arlo platform. During migration some accounts required creating new credentials. If your old Netgear password no longer works use the Forgot Password option with the same email address to set a new password on the Arlo platform. The email address should be the same as your old Netgear account.
Verify Two-Factor Authentication
If you have two-factor authentication enabled on your Arlo account the verification code must be entered within 60 seconds of being generated. On your phone go to Settings then Date and Time and ensure the clock is set to automatic. Request a new code and enter it immediately when it arrives. If using an authenticator app ensure the app clock is synced by opening the app settings and tapping Sync Time.
Wait After Failed Attempts
If you have attempted to log in multiple times with the wrong credentials Arlo may have temporarily locked your account. Close the Arlo app and wait 30 minutes. Then try one careful login attempt with the correct credentials. Continued rapid login attempts extend the lockout period. One patient attempt after the cooldown is more effective than many rapid tries.
Check for Compromised Account
If you did not change your password but it suddenly stopped working your account may have been compromised. Use the Forgot Password feature to reset immediately. After regaining access change your password to something unique and enable two-factor authentication. Check your Arlo account for any unauthorized changes like new shared users, modified camera settings, or changed subscription plans. Remove any unauthorized access.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Use a password manager to store your Arlo credentials. Error 1005 is most often simply a wrong password. A password manager eliminates this issue and also helps you use a strong unique password for your Arlo account which is important since it controls access to your home security cameras.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
- Password is incorrect due to typo or forgotten change
