OneDrive is a cloud storage service that allows you to store, share, and access your files from anywhere. It provides 5 GB of free cloud storage, and you can upgrade to a Microsoft 365 subscription to get up to 1 TB of storage. With OneDrive, you can automatically back up your phone's photos and videos, share files and folders with friends and family, and access your files on all your devices.
You can sign in to OneDrive using your Microsoft account, and you can also use the OneDrive app to view and share OneDrive files, photos, and videos on your phone or tablet. The app also allows you to scan and save documents, business cards, receipts, and whiteboards, and you can mark up, sign, and send docs right from the OneDrive mobile app.
OneDrive also provides security features such as Personal Vault, which lets you protect your important files with identity verification, and ransomware detection and recovery. You can also use OneDrive to edit and collaborate on Office documents in real-time, and you can access your Office apps on iPad, iPhone, and iPod touch.
To get started with OneDrive, you can sign in to office.com and select OneDrive to access your files. You can also download the OneDrive app from the App Store or the Google Play Store.
