Managing personal Outlook.com account settings, security, and privacy
Hi,
Outlook.com does not provide a supported option to bypass mandatory security verification and sign in using only an email address and password.
If you want to reduce verification prompts:
Visit Microsoft Account Security.
Review your available verification methods.
Set up Microsoft Authenticator or another supported sign-in method.
If offered, select Don't ask me again on this device when signing in from a trusted personal device.
Avoid private browsing and clear-cookie settings that remove your trusted-device session.
If you have lost access to your verification method, use the Microsoft Account Recovery Form.
I hope this information helps. If you have any more questions, don't hesitate to reach out. Wishing you good luck!
