In the security & compliance centre you can view and filter the audit log by many products/activities. But one thing I can't do is find a filter that shows only login success/failure messages (and other related activities). Is this possible?
Or PowerShell. In any case, if you are interested in Login events, best use the Azure AD logs directly from the Azure portal, they offer much more detailed information, and are populated faster compared to the ones in the SCC.
