Protect: protected mode
Protected mode is a mode that Yandex Browser enables on bank and payment system web pages to make electronic payments more secure. In protected mode the browser enables strict verification of certificates. If the certificate is verified, the browser disables extensions and changes the interface. Protected mode is part of the Protect integrated security system.
Check certificates
In protected mode, Yandex Browser enables strict verification of HTTPS certificates. Protected mode is not enabled if:
- There are problems with a certificate; for example, a bank certificate is expired, invalid or untrusted.
- An unknown certificate installed to your operating system by a program or the network administrator is used.
- A certificate installed by special software is used.
Alert
If protected mode has not been enabled, it is unsafe to make electronic payments and we do not recommend doing this.
Disabling extensions
In the protected mode, Yandex Browser disables all extensions except password managers verified by Yandex. This is to prevent malicious extensions from stealing or tampering with your payment information.
The extensions are re-enabled when you exit protected mode.
Enabling the mode
Protected mode is enabled by default when payment pages are open. The upper panel and tabs of Yandex Browser turn dark gray, and the name of the mode and the 
icon appear in the SmartBox.
If you have opened an online payment page and don’t see changes in the interface, enable protected mode manually.
You can add any page that uses HTTPS to the list for enabling protected mode.
- In the SmartBox, click the connection status icon.
- The Protect panel opens. In the connection status section, click Learn more.
- In the Permissions section, enable Protected mode.
Alert
If protected mode is not enabled, there are most likely problems with the site certificate. It’s better not to make payments on this page. We recommend that you open the Protect panel, read the information about using the certificate and assess the risk of theft of your payment information.
