One-tap login
One-tap login signs a customer in by confirming their number with the strongest check the phone and network allow, so most customers type nothing.
Glossary, A to Z
In DeepID’s order: silent network verification, then the SIM check, where the phone sends one text from its own SIM, then Aadhaar consent, then a one-time code as the last fallback. The first that verifies ends it, and the bank’s server redeems a single-use token before signing anyone in.
