Exchange Bank Account Access: How to Sign In Securely
This is a guide. There is no sign-in form on this page. Exchange Bank requires every customer to authenticate through the canonical sign-in flow on exchangebank.at — a five-step process with multi-factor authentication, 15-minute idle timeout and device-aware lockout after five failed attempts. The sequence below walks through the secure flow, prerequisites and recovery paths.

Customer Care Security Controls
Before You Sign In: Prerequisites
Three items every user should verify before the first sign-in of the day.
Active Online Banking Enrolment
If you have never signed in to Exchange Bank before, enrol first via the enrolment flow at the sign-in enrolment guide. First-time Exchange Bank enrolment requires your account number, Social Security number last four, and a registered email and mobile phone for MFA delivery. New enrolments typically complete in under five minutes.
Recognised Device and Current Browser
Use a browser released in the last 12 months with automatic updates enabled — Chrome, Edge, Safari or Firefox. On mobile, install the Exchange Bank mobile app from the App Store or Google Play. A recognised device avoids an MFA challenge on every Exchange Bank sign-in; MFA still fires on sensitive actions.
MFA Device Available
Keep the MFA-registered mobile phone accessible for SMS one-time codes or authenticator-app TOTP generation. Biometric sign-in on the Exchange Bank mobile app supports Face ID, Touch ID and Android fingerprint — the biometric check stays on-device and never crosses to the bank.
Five-Step Secure Sign-In Procedure
The canonical flow used for every Exchange Bank digital banking session.
-
Step 1 — Open exchangebank.at
Navigate to exchangebank.at in any current browser. Check that the browser address bar reads exactly exchangebank.at and that the padlock icon confirms a valid TLS certificate. Bookmark the Exchange Bank URL or use the Exchange Bank mobile app to avoid typosquat domains. Never sign in from a link in an email, text or social media message.
-
Step 2 — Click Sign In
Select the Exchange Bank Sign In link in the site header or the primary CTA on the hero section. The sign-in panel loads over TLS 1.3. Return users see the last successful sign-in date and time on the Exchange Bank sign-in screen — a quick visual check for session tampering.
-
Step 3 — Enter User ID and Password
Enter your Exchange Bank online banking User ID (the identifier chosen at enrolment, not your account number) and the associated password. Passwords are case-sensitive and must be 12 or more characters with mixed case, a digit and a symbol. Use a password manager to avoid reused or weak passwords. Do not save the password in shared browser storage on a public computer.
-
Step 4 — Approve Multi-Factor Authentication
If the device is unrecognised or the action is sensitive, an Exchange Bank MFA challenge appears. Choose SMS one-time code, voice callback, authenticator-app TOTP or mobile-app push. Codes expire in five minutes. Prefer authenticator-app codes to SMS where possible — SMS is vulnerable to SIM-swap attacks. Never read or type a code into a form that appeared from a link in an email.
-
Step 5 — Land on the Dashboard
Successful authentication opens the Exchange Bank account dashboard: balances, recent activity, transfer, bill pay, mobile deposit, card controls and alerts. Sessions expire after 15 minutes of inactivity. Sign out manually on shared devices — close the browser tab if possible. A secure sign-out is the last step of the Exchange Bank procedure.
Troubleshooting Common Sign-In Issues
Self-service paths before calling support.
Forgot Password
Click Forgot Password on the Exchange Bank sign-in screen, enter User ID and email on file, follow the reset link (valid 30 minutes), complete MFA, set a new password. If the email does not arrive, check spam and then call 1-800-995-4066.
Account Locked
After five failed attempts, the Exchange Bank account locks for 30 minutes. Wait and retry, or call customer care to verify identity and unlock immediately during business hours.
MFA Code Not Arriving
Check mobile signal and spam filters on SMS. For authenticator-app TOTP, ensure device time is synchronised. Call 1-800-995-4066 if codes remain undelivered — the Exchange Bank support team can initiate an out-of-band verification and re-enrol the MFA device.
Browser Compatibility
Update to the latest browser release, clear cache and cookies for exchangebank.at, disable blocking browser extensions, and retry. Internet Explorer is not supported for Exchange Bank online banking. Private or incognito mode works but will trigger a new-device MFA challenge.
Biometric Sign-In Not Working
Confirm the device supports Face ID, Touch ID or fingerprint in the operating system settings. Ensure the feature is enabled in the Exchange Bank mobile app settings. If the biometric fails, fall back to User ID and password.

Security Best Practices on Sign-In
Habits that measurably reduce credential-theft risk.
According to Consumer Financial Protection Bureau consumer-protection research and FDIC banking-security guidance, most deposit-account fraud losses on the customer side originate from reused passwords and phishing responses. The following habits cut both risks sharply.
Use a password manager to generate a unique password for banking. Enrol an authenticator-app TOTP alongside SMS as a fallback. Verify URL before entering credentials — typosquat domains mimic banks routinely. Never approve an MFA push you did not initiate. Sign out on shared devices. Enable real-time push notifications for sign-in events so a stolen credential attempt generates an instant alert.

Customer Sign-In Experiences
Three clients on the secure-access flow.
"Biometric Sign-In Is a Relief"
"Set up Face ID on the mobile app three years ago. Sign-in takes about two seconds. No typing a password on a touchscreen, no SMS codes on a normal day, and if the MFA does trigger I know something is different about the session. The sign-in flow is the single feature I would miss most."
— Pierre D., Account Holder (Santa Rosa, CA)
"Caught a Phishing Attempt"
"Received an email claiming my account was locked with a sign-in link. The URL was exchangebànk.at with a subtle accent. Because I always type the domain manually and check the padlock, I noticed instantly. Reported to fraud@exchangebank.at. The security team confirmed the campaign was targeting customers that week."
— Juliana F., Customer (Sonoma, CA)
"Password Manager Plus TOTP"
"Pairs password manager with authenticator-app TOTP. Zero sign-in friction on recognised devices, a TOTP code on new ones, and the app locks any sensitive action behind a second check. Have not been locked out, have not had a credential reused, and every sign-in event pushes a notification so I would notice an attack immediately."
— Isabel R., Customer, Mendocino Supply Co. (Windsor, CA)
