Why you are being asked: Identity rules are national, not global. The Trust Center lets you verify according to specific regional laws — the EU, US, India, Singapore and others — rather than forcing one model on everyone.
The simple rule: Choose the jurisdiction whose services you actually need. If you are in Germany applying for European services, verify under the EU module.
What the EU module targets: eIDAS is the European framework for electronic identification and trust services, and "High" is its strongest assurance level. Meeting it is why NFC verification of a biometric passport exists in the flow.
What the US module targets: The NIST trust framework, which treats identity proofing and authentication strength as separate questions — so a strong login does not by itself imply a thoroughly proofed identity.
You are not locked in: You can switch between global and regional verification modules in the Trust Center at any time.
A note on FATF: The financial-crime trust framework is also supported, which is what makes the identity usable in bank-grade contexts.
