Android: Accessibility authorisation
Do you use Accessibility for apps requiring authorisation? Please make sure you trust these apps.
What purpose does this authorisation serve?
Accessibility authorisation is intended primarily for persons with visual and hearing impairment, speech disorders or physical disabilities in order to simplify their work with the phone and with some apps.
For example, authorisation enables the font size to be changed in some apps, the phone to be controlled by voice or the keyboard layout to be adjusted, as well as the reading out of text displayed on the phone screen.
What is risky about this authorisation?
Applications with Accessibility authorisation enabled can read (as well as record) the displayed text and thereby get access to the information viewed by the user, such as text messages and conversations, phone numbers and contacts. In the context of banking apps, this may include sensitive data such as names, account numbers, transactions or balances.
Where to check which apps use Accessibility authorisation and how to disable it?
You can find a list of apps in the menu Settings - Accessibility - Services. You can also switch authorisation for individual apps on or off in this menu.
How do I recognise if an app is misusing my authorisation?
You should consider what the app is for and if the use of such authorisation makes sense. The app’s developer should be able to explain what the app uses the authorisation for - such an explanation may be displayed directly in the app, available on the app page in Google Play or on the website of the company providing the app.
