Getting into your AB Bank account online
AB Bank's login portal is at www.abbank.com. Enter your username and password on the homepage, then click "Sign In". If you are logging in from a new device or location, AB Bank may send a verification code to your registered email or phone number — check both before assuming the code did not arrive.
If you have not yet set up online access, you will need your account number and Social Security number to register. The registration process takes about five minutes and creates your username and password. You can do this on the same login page by selecting "Enroll Now" or "New User".
AB Bank's mobile app is available on iOS and Android. Download it from the App Store or Google Play, then use the same username and password you created for the website. The app and website are linked to the same account, so any changes you make in one show up in the other.
Key Takeaways
- AB Bank's online login is at www.abbank.com; use your username and password to sign in.
- New users must register with their account number and Social Security number before they can log in for the first time.
- AB Bank may ask for a verification code sent to your email or phone if you log in from an unfamiliar device or location.
- The mobile app uses the same login credentials as the website and syncs your account information across both.
What to do if you forget your password
Click "Forgot Password" on the AB Bank login page. AB Bank will ask you to enter your username or the email address tied to your account. You will then receive a password reset link by email — this link usually works for 24 hours.
Click the link in the email and create a new password. Your password must meet AB Bank's requirements, which typically include a minimum length, at least one number, and at least one uppercase letter. Once you submit the new password, you can log in immediately using it.
If you do not receive the reset email within a few minutes, check your spam or junk folder. If it is not there, contact AB Bank's customer service by phone or visit a branch in person with a photo ID to reset your password through a representative.
Two-factor authentication and security codes
AB Bank can send you a one-time code each time you log in, or only when you log in from a new device. You choose this setting in your account security preferences. The code arrives by text message or email, depending on what you selected during setup.
Enter the code on the screen after you type your password. If you do not receive it within two minutes, request a new code — most systems allow you to do this directly on the login page. Do not share this code with anyone, including AB Bank staff; AB Bank will never ask for it.
If you lose access to the phone number or email where your codes are sent, contact AB Bank before you try to log in again. They can update your contact information and remove the two-factor requirement temporarily so you can regain access to your account.
Troubleshooting login problems
If you see an error message saying your username or password is incorrect, make sure Caps Lock is off — passwords are case-sensitive. Try logging in again. If the message persists, use the "Forgot Password" link to reset it.
If your account is locked after multiple failed login attempts, wait 15 to 30 minutes before trying again. AB Bank locks accounts temporarily to protect them from unauthorized access. If the account remains locked after waiting, call customer service or visit a branch.
If the website or app is not loading at all, check your internet connection and try a different browser or device. Clear your browser's cache and cookies, then try again. If the problem continues, AB Bank's website status page or social media accounts usually post updates about outages.
Logging in on a shared or public computer
Avoid logging into your AB Bank account on a shared computer, library computer, or public Wi-Fi network. If you must, log out completely when you are finished — do not just close the browser. Select "Sign Out" or "Log Out" from your account menu to end your session.
Do not check the "Remember Me" or "Stay Logged In" box on a shared device. These options keep your login active, which means the next person to use that computer can access your account without a password.
After logging out on a public computer, clear your browser history and cache if the computer allows it. On your own device, you can safely use "Remember Me" if you want faster login next time, but only if no one else uses that device.
Accessing your account from outside the United States
AB Bank's website and app work from most countries, but some banks block logins from certain regions for fraud prevention. If you are traveling and cannot log in, contact AB Bank before you leave to let them know where you will be. They can flag your account so the system does not block you.
Using a VPN (virtual private network) to log in from abroad may trigger additional security checks or block your login entirely, because VPNs can look suspicious to fraud detection systems. It is safer to contact AB Bank directly if you cannot log in while traveling.
If you are locked out while abroad, customer service can verify your identity over the phone and reset your access. Have your account number, Social Security number, and a recent statement or card handy when you call.
Frequently Asked Questions
Can I use my debit card number to log in instead of a username?
No. AB Bank requires a username and password to log in online. You set up your username during enrollment. If you cannot remember it, call customer service and they can tell you what it is or help you create a new one.
What should I do if I see a login page that looks different than usual?
Do not enter your information. Phishing pages mimic bank websites to steal passwords. Close the page and go directly to www.abbank.com by typing the address into your browser yourself, or call the number on the back of your debit card to report the suspicious page.
Is it safe to save my password in my browser?
Only on a device that only you use. Browsers store passwords in a way that is difficult but not impossible for others to access. On a shared device, do not let your browser save your banking password. On your personal phone or computer, it is reasonably safe.
Can I log in to multiple accounts at the same time?
Most banks allow you to log in to one account per session. If you manage multiple accounts, you can log out of one and log in to another, or contact AB Bank to ask whether they support multi-account access in a single session.
What happens if I do not log in for a long time?
Your login credentials remain active. However, if you have not logged in for several months or years, contact AB Bank to confirm your account is still open and active. Some banks close accounts that show no activity for extended periods.
