Hi there, @PracticeAdmin.
Thanks for joining the Community today. I can share some information about why you need to verify your account upon logging in to QuickBooks Online.
Your account's security is our top priority. Passwords, on their own, are not always secure if someone gets your password, they can access your account and make unauthorized changes. This is why we enhanced our security and added multi-factor authentication and Two-step Verification.
Multi-factor authentication is an extra layer of security, which you may be asked to enter a one-time confirmation code, which provides extra protection for your password. The code will be sent to your email or mobile device. However, you have the option to opt these verification by following the steps that colleague MichaelDL provided above.
If you need additional assistance about this concern feel free to reach Customer Care Team. You can reach them through the contact details found in this link: Contact the QuickBooks Online Customer Support team.
These information should get you moving today.
Be sure to let me know how else I can empower you to make QuickBooks work the way your business needs. Thanks for coming to the Community, wishing you continued success.
