A Parking Permit Portal is to be implemented for general public users where zero administration for users is required. With user name and password, it can open a can of worms; Security issues, operation nightmare, customer service overload are the major concerns to provide a web portal to thousands of users.
Mandala BEST has implemented passwordless access to the permit portal for councils in Australia.
When user accesses the porta, the user provides email into which OTP (One-time-passcode) is sent.
The user then provide the passcode received to be able to access the portal.
