# Using CordLine on the Web, Phone, and Multiple Devices

This article explains what's shared across devices, what differs between the app and the browser, and what to expect on a slow connection.

## What's shared everywhere

Your account, posts, connections, and messages are the same no matter where you sign in — the app and the website both talk to the same CordLine behind the scenes. There's nothing to sync manually.

## What's different on the web

- **No push notifications.** Push alerts are a mobile app feature. On the web, you'll rely on email, text, and in-app notifications instead — see our article on managing your notification preferences.
- **No biometric unlock.** Face ID and fingerprint unlock are mobile-only.
- **No video uploads.** You can add photos to a post on the website, but videos can only be added from the mobile app.

Everything else — posting, messaging, reactions, Phoebe — works the same on both.

## Using more than one device

You can be signed in on your phone, a tablet, and a browser all at once. Turn on notifications separately on each device you want to hear from, since that setting is per device, not per account.

## On a slow or unreliable connection

CordLine needs a connection to post, load your feed, or send a message — there's no offline mode for creating content. Photo and video uploads are the most affected by a weak connection; text loads faster than media. If something seems stuck, check your connection before assuming something's broken.

## Tips

- **The app is generally the more complete experience** on a phone — biometric unlock and push notifications are both mobile-only.
- **The website is a good fallback** if you're on a device without the app installed, or troubleshooting something that seems app-specific.
