One drive is more or less built into Windows 10 and 11. If you have the Home version of Windows, you're forced to create a microsoft account when you log in first. After that, just give One-drive the same username/password and it should just work.
Plus most Chromium based browsers (read everything except Safari and Firefox, including Opera and Edge) have a cloud storage system using either google's servers or some other server. And there's DropBox, Box, GoogleDrive, iCloud, and other cloud hosting services for files and photos. Even Amazon is in on the gig now.
If you're using Windows, using One-Drive is no brainer, since it's very well integrated into the OS and Office products.
