Is Edge encrypted?
No. Microsoft can read the favorites, history and open tabs Edge syncs, and it doesn't say that only you hold the key to your synced passwords. Edge does connect to sites securely by default.

- Who holds the keys
- Microsoft holds the keys to synced favorites and history, and it doesn't describe a key that only you hold for passwords, as of 25 October 2026.
- What Microsoft can still see
- Your synced favorites, history and open tabs, plus your device's name, make and model, with an account ID attached to all synced data.
On business plans, Edge encrypts most synced data on your device before it syncs, with keys managed through your organization's Microsoft protection settings, and admins can bring their own key.
Stop syncing your history
- In Edge, select Settings and more › Settings › Profiles › Sync.
- Turn off the toggles for History and Open tabs.
- Turn off Passwords too if you'd rather keep them on this device only.
This doesn't seal anything. It stops new history and tabs from going to Microsoft. To delete what's already synced, Microsoft points you to the devices page of your Microsoft account.
Email is worth checking next: Gmail, Outlook and iCloud Mail can all read your mailbox. See which email services can.
Is Edge sync end-to-end encrypted?
No. Microsoft says synced data is encrypted on the way and stored encrypted on its servers1. Passwords and addresses get an extra layer of encryption on your device first1. Microsoft doesn't describe a key that only you hold for any of it, as of 25 October 2026.
For work accounts, Microsoft explains that history and open tabs aren't encrypted on your device before they sync, because its servers build your history from your open tabs2.
Can Microsoft see my Edge passwords?
Microsoft says your passwords are encrypted on your device before they sync1. It doesn't say who holds that key, or that it can't read them, as of 25 October 2026.
Passkeys work differently. Since Edge 142 on Windows, passkeys sync protected by a Password Manager PIN that you set and need on each new device5.
Does Edge use HTTPS by default?
Yes. Microsoft says that since Edge 120, Edge tries to upgrade unsecured links to secure ones whenever it can3. Captive portals, IP addresses and local network names are left out3.
To choose what Edge syncs at all, go to Settings › Profiles › Sync and use the toggles for each kind of data4.
