Coworking, members clubs and co-living all share a common challenge: physical space access for a high-churn user base. OTP is the Authentication-as-a-keychain that ties digital booking to physical entry.

Why Coworking Apps Use OTP

  • Member onboarding without a separate IT account.
  • Door-unlock without distributing key cards.
  • Guest-pass issuance.
  • Meeting-room booking confirmation.

OTP Flows

  1. Member sign-up OTP.
  2. Door-unlock OTP per session.
  3. Guest-pass dual OTP (host + guest).
  4. Meeting-room confirmation OTP.
  5. Membership renewal SMS.

Door-Unlock OTP

Tap “Open door” in the app, system emits 60-second OTP to the member’s phone, the door panel scans the code or accepts manual entry. Logged for compliance + member analytics.

Guest-Pass OTP

  1. Member taps “Invite guest”, enters guest phone.
  2. System generates a time-windowed access pass.
  3. Host OTP authorises; guest OTP grants access.
  4. Both OTPs reference the same accessPassId.

Meeting-Room Booking

Confirmation SMS at booking; reminder OTP 15 minutes before; door unlock OTP at start. Three OTPs that chain to the same booking ID.

FAQ

StartMessaging ships sub-second SMS — essential for door-unlock UX where 5-second latency means embarrassed members at the entrance.
