The requirement to enter a verification code each time you click the update button for bank transactions in QuickBooks Online (QBO) depends on the security settings and protocols established by your bank, JL. Allow me to provide a comprehensive explanation regarding this process and what it entails.
Some financial institutions now enforce multi-factor authentication (MFA) as part of their security measures to safeguard your accounts. This industry-standard practice enhances account security by requiring an additional verification step, such as entering a code sent via text.
As a result, QBO follows the security standards set by your bank, which may include frequent MFA prompts. The need to enter a new code every time you update your bank transactions—even within a short time frame—reflects the security policies put in place by your bank.
