I am fully aware of what vpn services to use and not. I am not using Express VPN, I am simply doing research for a master thesis, when I came across these results from Express VPN. If you have any ideas or corrections, please let me know why a VPN provider would need to have access to these permissions.
Screenshot is from Exodus service, which let’s you view what exactly perimissions and trackers each app uses. You can check out the results and the tool for yourself here: https://reports.exodus-privacy.eu.org/en/reports/com.expressvpn.vpn/latest/
There are Bluetooth FIDO security keys out there for 2FA, like: https://thetis.io/products/fido2-ble-security-key. Some implementations can also use a phone, running an app via BLE. Not sure if they use it, but that could be one reason it’s asking for that permission.
Camera permission may be needed for scanning QRCodes to set up 2FA.
