Login Page Not Loading
If the Brex login page does not load correctly, first determine whether the problem affects only one browser or the entire service.
Brex recommends trying a current browser, checking extensions, clearing browser data and testing another device when appropriate.
Incorrect Email or Password
Confirm that the email being entered is the one actually associated with the Brex user account.
If the password has been forgotten, use the official reset flow rather than repeatedly guessing.
Verification Email Not Arriving
Check spam and filtered folders and confirm that the user is viewing the correct email account.
Corporate email administrators may need to allow Brex verification senders.
Brex also recommends waiting a few minutes after choosing Resend email and then using the newest verification message.
Expired Verification Links
A device-verification link can expire.
Brex recommends starting the sign-in process again to generate a new verification message.
Do not repeatedly use an old verification email after a newer one has been sent.
Device Verification Failure
Open the verification email on the same device involved in the login attempt when possible.
A mismatch between network/IP conditions can prevent verification from completing.
Authentication Code Errors
An authenticator code can appear correct but still fail when the device clock is inaccurate.
Set the date and time automatically and verify that the code belongs to Brex.
Browser Cache and Cookie Issues
Corrupted or outdated browser state can interfere with authentication.
Brex recommends clearing browser cache, cookies and history as one troubleshooting option.
Remember that clearing cookies may cause previously trusted devices to require verification again.
VPN, Proxy and Firewall Issues
Corporate VPNs, proxies, security filters and firewalls can block content required by the Brex dashboard.
Brex advises users to confirm that the network is not restricting dashboard access and to involve the company's IT team where corporate filtering is in use.
Incorrect Device Date and Time
Brex authentication relies on time-sensitive security tokens.
Brex states that an incorrect computer or device clock can prevent sign-in completely.
The device should reflect accurate current local time.
Mobile App Sign-In Problems
If Brex works in a browser but not the mobile app, the issue may be specific to the app or device.
Confirm that the app and operating system are current, verify network access and check whether Brex is reporting a mobile-service incident.
