This article explains how to switch between your Personal and Business profiles in the KAST app. You’ll learn how the account switcher works, when additional authentication may be required, what changes when you switch, and what happens when you sign out.
How Does Switching Between Personal and Business Work on KAST?
KAST Personal and KAST Business are separate login identities under one KAST user. Once your Business account has been created and approved, you can switch between your Personal and Business profiles directly inside the KAST mobile app.
Switching is silent only when your device already has a valid session for the profile you’re switching to. If not, KAST may ask you to complete OTP re-authentication for that profile’s email address. Unlocks are device-specific, so you may need to authenticate again when switching on another device.
On web, KAST Business is currently the available context.

Why Am I Being Asked to Complete MFA When Switching?
For security reasons, KAST may ask you to complete OTP re-authentication when switching into a profile that is not currently unlocked on your device.
This may happen:
- The first time you open your Personal profile on that device
- The first time you open your Business profile on that device
- When your device no longer has a valid refresh token for the profile you’re switching to
Once authentication is completed for that profile on that device, you should be able to switch back and forth without additional prompts while the valid session remains active.
What Happens When I Switch Profiles?
When you switch profiles, the app updates to show the selected context:
- Balance view changes to the selected profile’s balance.
- Cards shown are for the selected profile. In Business, this may include company or employee cards, depending on your role.
- Payouts, transfers, and card controls apply only to the profile you are currently using.
Your Personal and Business profiles are separate ledgers. Balances, cards, and transaction histories are not shared between them.
What Happens When I Sign Out of KAST?
Signing out ends your KAST access on that device. The next time you open KAST, you’ll need to sign in again before accessing your available Personal or Business profile.
Why Can’t I See the Business Toggle?
The Business toggle usually only appears if your account has access to a KAST Business profile.
You will see the toggle if:
- You created a KAST Business account
- You accepted a Business invite
- Your account has been added to a Business team
- Your Business setup or access is active
If you believe you should have access but don’t see the toggle, make sure your app is updated and check whether your Business invite or setup is complete.
What Happens If My Business Access Is Removed?
If your Business access is revoked or deleted:
- You will lose access to the Business profile
- The Business toggle may disappear
- Your Personal profile will still remain active and accessible, if you have a Personal profile
Frequently Asked Questions
Why Was I Asked for an OTP When Switching?
KAST may ask for an OTP when the profile you’re switching to is not currently unlocked on that device. The OTP is sent to the email address for that profile.
Does Signing Out Affect Both Profiles?
Signing out ends your KAST access on that device. You’ll need to sign in again before opening your available Personal or Business profile.
Can I Access More Than One Business Profile?
At this time, the Business toggle appears for the Business profile connected to your account. If you expect access to another Business profile, check with the person who manages that Business account.
Does Switching Profiles Move Money or Transactions Between Personal and Business?
No. Switching profiles only changes the context you are viewing in the app. It does not transfer balances, cards, or transactions between Personal and Business.
Can My Business Team See My Personal Account Activity?
No. Your Personal account activity and Business account activity are treated as separate contexts. Business Owners or Admins may see Business-related activity based on their permissions, but they can’t access your Personal transactions through KAST Business.
What Should I Do If Switching Doesn’t Load Correctly?
Update the KAST app to the latest version, close and reopen the app, then try switching again. If the issue continues, contact KAST Support.
