Frequently Asked Questions

Why is my Outlook verification code not arriving via text message?

This can happen due to mobile carrier blocks on automated shortcode SMS messages, unexpected network delays, or an outdated phone number linked to your Microsoft account.

Can I bypass the Microsoft Authenticator app if I lose my phone?

You cannot entirely bypass the multi-factor authentication, but you can select 'Sign in another way' on the login screen to use backup methods, such as an alternate email or recovery code, if they were previously configured.

How long should I wait for a Microsoft verification code to arrive?

Typically, verification codes arrive within a few minutes. If you have not received it after 15 minutes, request a new code, as the original one may have expired or failed to deliver.

Can I use WPS Office without an account if I am locked out of Microsoft?

Yes, WPS Office can be used offline to view and edit your local documents without needing complex account verifications, making it a great fallback when experiencing login issues.
