What You Need to Begin Your au ID Experience
- An au ID account. If you are an au or UQ mobile customer, your initial au ID may be your mobile phone number. Non-au customers can register using an email address.
- For new au/UQ mobile contracts made after February 2015, your initial au ID and password can be found in your 'Service Start Guide' (ご利用開始のご案内). For older contracts, you may need to follow specific registration steps depending on your service.
- A device capable of internet access (smartphone, tablet, or PC) and a web browser.
Accessing Your au ID Online Portal
- Navigate to the official au ID login page (id.auone.jp).
- Enter your au ID. This can be your au mobile number, a voluntary ID you registered, or an email address. Then, input your password.
- If prompted, complete the two-step verification. This often involves entering a verification code sent to your registered phone number via SMS.
- Alternatively, if you have enabled biometric authentication (fingerprint or facial recognition) on your device, you can use this method for a password-free login.
- If attempting to log in from a device not configured for biometric authentication (e.g., a PC), you might need to activate the 'password login setting' through a device where your biometrics are already set up.

Addressing Login Roadblocks for Your au ID
⚠️ Forgot au ID or Password
Cause: You cannot recall your au ID or the password associated with it.
Solution: If you've forgotten your au ID, remember it might be your mobile phone number or a registered email address. You can attempt to retrieve it via the au ID member information site. To reset your password, visit the login page and select the 'Forgot password' option. You will typically be guided through a process that involves verifying your identity, often by entering your phone number or email and a secret four-digit PIN, followed by receiving a verification code via SMS to set a new password.
⚠️ Login Errors (e.g., CCAE or HNYE codes)
Cause: The system displays specific error codes (like CCAE or HNYE) during the login attempt.
Solution: First, meticulously verify that your au ID and password are entered correctly, paying close attention to case sensitivity and ensuring only half-width alphanumeric characters are used. Be wary of browser auto-fill functions, which might insert incorrect previous entries. If these errors persist, particularly with specific codes, it is highly recommended to reach out to au chat support for specialized assistance.
⚠️ Two-Step Verification Code Not Received
Cause: The SMS or email containing the two-step verification code does not arrive.
Solution: Confirm that the phone number or email address registered for your au ID is accurate and up-to-date. Check your email's spam or junk folders, and ensure you haven't blocked messages from unknown senders. If the code still doesn't arrive, contact au customer support for troubleshooting.
⚠️ Biometric Login Failure or Login from Unregistered Device
Cause: Your fingerprint or facial recognition fails, or you are trying to log in from a new device not set up for biometrics.
Solution: If biometric login is not working, ensure your device's biometric sensors are clean and functioning properly. For logging in from a new or unregistered device (like a PC), you might need to enable the 'password login setting.' This configuration typically needs to be performed on a device where your biometric authentication is already successfully set up.
⚠️ General Login Difficulties
Cause: You are experiencing unspecific problems preventing a successful login.
Solution: Try these general troubleshooting steps: ensure your web browser (e.g., Google Chrome) is updated to its latest version, temporarily disable Wi-Fi and attempt logging in via mobile data (4G/5G), clear the cache and data for the specific app you are using, or uninstall and reinstall the app. Sometimes, a simple device restart can resolve underlying issues.
Fortifying Your au ID Digital Security
- 🔒 Always Verify the URL: Before entering your au ID and password, always double-check the website address in your browser. Ensure it is the legitimate au ID site (id.auone.jp) to avoid phishing scams. Never click suspicious links.
- 🔒 Create Strong, Unique Passwords: Use complex passwords that combine uppercase and lowercase letters, numbers, and symbols. Avoid easily guessable information like birthdays or sequential numbers. Never share your password with anyone, and refrain from writing it down. Consider changing your password regularly.
- 🔒 Enable Two-Step Verification: Activate two-step verification (also known as two-factor authentication) for an extra layer of protection. This feature requires a verification code, usually sent to your phone via SMS, in addition to your password, significantly reducing the risk of unauthorized access.
- 🔒 Utilize Biometric Authentication: On compatible devices, set up and use fingerprint or facial recognition for a more secure and convenient login experience. This method protects against password theft.
- 🔒 Log Out on Shared Devices: If you use your au ID on public or shared computers (e.g., at work or an internet café), always remember to explicitly log out of your account to prevent others from accessing your information.
- 🔒 Monitor Account Activity: Regularly review your au ID account activity for any unfamiliar logins or transactions, especially for services like au PAY. Be alert for unexpected notifications and promptly investigate any suspicious signs of unauthorized access.
