Introduction

This article explains the most common login errors users may encounter on Coinlocally and provides clear steps to resolve them. These issues usually relate to incorrect credentials, invalid OTP codes, or Google Authenticator synchronization problems.

Common login errors and how to fix them

“User not found or your password is incorrect”

This error appears when the system cannot match your login credentials.

To fix it:

• Make sure your entire email address is typed in lowercase.
• Double‑check that your password is entered correctly.
• Try logging in again after confirming both fields.

“Your One Time Password is Invalid” (2FA)

This error occurs when the Google Authenticator code is incorrect or expired.

To fix it:

• Google 2FA codes are valid for only 30 seconds — enter the code within the valid time window.
• Ensure you imported the correct 16‑digit key for your Coinlocally account.
• Make sure the time on your mobile device is synchronized with Google’s servers.

(Incorrect device time causes invalid codes.)

If none of the above steps solve the issue, you will need to reset your Google Authentication.

Additional notes

• Incorrect device time is one of the most common causes of invalid 2FA codes.
• If you recently changed phones, ensure you transferred your Google Authenticator properly.
• Always store your 16‑digit backup key securely.

Common Issues

• Entering uppercase letters in your email may cause login failure.
• Using an old or incorrect 16‑digit 2FA key will generate invalid codes.
• Unsynced device time leads to repeated OTP errors.

Tip: Enable automatic time synchronization on your phone to avoid 2FA issues.
