OTP Listener

OTP Listener is a secure, web dashboard that puts you in complete control of one-time passwords (OTPs):

Real-Time OTP

Clients pull the latest OTP for a given mobile number. All requests are guarded by per-token credentials (token + password) and rate-limited by a configurable mobile-number cap.

Per-Hour Mobile-Number Limits

Prevent abuse by setting how many distinct phone numbers may request OTPs each hour. Once the max is reached, further requests return a clear “mobile number limit reached” error until the next hour’s window.

Preset-Number Whitelisting

Turn on “Use Preset” mode to restrict OTP delivery to a fixed list of up to N pre-registered numbers — ideal when only a handful of devices should ever see your OTPs.

User Dashboard

• Live OTP Feed: see all OTPs you’ve received in the last 24 hours, with Indian Standard Time (IST) timestamps down to the millisecond.
• Usage Meter: “Mobile Limit” vs. “Used This Hour” gives you instant visibility on your consumption.
• Preset Toggle & List: enable or disable whitelist mode, add/remove numbers on the fly (max N).
• Membership Countdown: watch days remaining until your token expires.
• Password Management: change your token password anytime.
