Power BI Desktop logging out

Hi yesoriginal ,

Since the issue persists only with your main Power BI account while another account works fine on the same device, it looks like the behavior is linked to that account’s authentication settings rather than the Power BI Desktop client.

You can try the following additional steps:

1. Clear Microsoft identity cache by sign out from Power BI Desktop and close all Microsoft apps.

   Delete all files in the “Cache” folder, then restart Power BI Desktop and sign in again.

2. If the “Remember MFA on trusted device” option is disabled, or if reauthentication is enforced frequently, this can cause repeated login prompts. You may want to confirm this with your IT or Azure AD (Entra ID) administrator.
3. Try Power BI Desktop (Store version) : It uses a newer authentication flow and can help resolve persistent sign-in loops.

If the issue still continues, I’d recommend checking with your organization’s Entra ID admin to review your account’s token or session lifetime policies.

Thank you.
