TrustVault supports iPhones with Touch/Face ID. Here's a list a list of the ones we support:
- iPhone 5S (2013)
- iPhone SE
- iPhone 6
- iPhone 6 Plus
- And all iPhones newer than above.
This is because we rely on the "Secure Enclave" which was introduced with the iPhone 5S in 2013. Learn more about this on the Apple website here.
