California Business Bank Computer System Upgrade.

March 21st – March 24th, 2019

Important Information About Your Mobile Banking


At California Business Bank, we are committed to providing the best for our customers—the best service, the best security, and the best website for all of your banking needs.

In an effort to improve the efficiency of our operations and continue to supply our clients with exceptional products and services, California Business Bank will undergo a conversion of its core computer operating system at the close of business on

Thursday, March 21st, 2019 through Sunday, March 24th, 2019.

Our goal is to make this transition as smooth as possible for our clients. All aspects of banking will be affected, including online access, mobile, bill payment, debit card system and external transfers. With this in mind, there are a few things you need to know:


Mobile banking access will be unavailable from 11:00 a.m. PDT on Thursday, March 21st through 10:00 a.m. PDT on Monday, March 25th.
For the first 12-15 logins to mobile banking users will experience requests to respond to multiple security questions.
The heightened security steps should be expected until full device profiling is completed and the algorithms establish confidence in the user’s identity. This process cannot be bypassed for any user or implementation.
Approximately within the first week of new enrollments, users may be prompted to input a security code or answer questions multiple times. This is due to “device profiling”, set up to ensure proper authentication of user, device, and locale.

NOTE: After initial profiling is completed, additional security (i.e. security question prompts, log-in with User ID and Password when attempting Quick Access logins) will occur when:

• A user is traveling outside his/her previously profiled geographic region.
• A user obtains a new device.
• Periodically on a random basis to ensure continued security for the user.
