What is TOTP?

  • It is an one-time temporary password (OTP), that is generated by an algorithm and valid only for 30 seconds. Because of this time variable characteristic, it is called TOTP.
  • TOTP is 8 digit long numeric strings.
  • TOTP is personal to the resident and is uniquely generated every 30 seconds for each resident separately.
  • With time-based OTP, the TOTP validation server and token generation app(like mAadhaar) use their respective system times to generate OTPs. The TOTP algorithm assumes that the system times are synchronized.
