How do I set a password for the app?
The Yandex.Direct mobile app will not ask for your username or password every time you launch it. If you want to protect your information from unauthorized access, you can set a password for the app. This password consists of four digits, has no relation to your Yandex username and is only used for signing into the app.
On the Profile screen, tap App password and activate the PIN code access option.
If you forget your app password, you can reset it. However, after doing so you will need to sign in again for all usernames. To reset the app password, tap Forgot your app password? on the sign in screen.
