Frequently Asked Questions

Why does Error Code 105 keep appearing even with correct credentials?
This often happens due to cached login data, an outdated app version, or temporary server issues. Try clearing the app cache, updating to the latest version, or waiting a few minutes before trying again.
Is my account hacked if I get Error Code 105?
Not necessarily. Error 105 typically indicates credential issues rather than security breaches. However, if you're certain your credentials are correct and you keep getting this error, contact your bank to verify account security.
Can I still access my account online if the mobile app shows Error 105?
Yes, try logging into your account through your bank's website using a web browser. If online access works but the mobile app doesn't, the issue is specifically with the mobile application.
How long does it take for a password reset to work?
Password resets typically take effect immediately after you complete the process. However, it may take 5-10 minutes for the change to sync across all banking systems, so wait a few minutes before trying the new password in the mobile app.
What should I do if I never received the password reset email?
Check your spam/junk folder first. If you still don't see it after 10-15 minutes, verify you're using the correct email address associated with your account, then contact your bank's customer service for assistance.
