Clients using an iPhone enabled with Face ID for 2 Factor Authentication purposes may disable that feature and authenticate with their PIN.
To change this setting on your iPhone:
- Go to the Settings screen and select Face ID & Passcode.
- After authenticating, select Other Apps.
- Locate the app titled IBKR and switch the setting to disable Face ID.
Once disabled, you will be prompted to authenticate by entering you 4 digit PIN on the phone.
