Controlling access based on passcode

A method for controlling access to a restricted physical space, the method being performed by an electronic lock, the method comprising:

• receiving an access request from a user device, the access request comprising a separate passcode, wherein the access request further comprises an encrypted set of at least one of valid one-time passcodes;
• decrypting the set of at least one of valid one-time passcodes;
• determining that the separate passcode matches a passcode in the set of at least one of valid one-time passcodes;
• and
• setting the electronic lock in an unlocked state.

An electronic lock for controlling access to a restricted physical space, the electronic lock comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the electronic lock to:
• receive an access request from a user device, the access request comprising a separate passcode, wherein the access request further comprises an encrypted set of at least one of valid one-time passcodes;
• decrypt the set of at least one of valid one-time passcodes;
• determine that the separate passcode matches a passcode in the set of at least one of valid one-time passcodes;
• and
• set the electronic lock in an unlocked state.

A non-transitory computer readable medium storing a computer program for controlling access to a restricted physical space, the computer program comprising computer program code which, when executed on an electronic lock causes the electronic lock to:

• receive an access request from a user device, the access request comprising a separate passcode, wherein the access request further comprises an encrypted set of at least one of valid one-time passcodes;
• decrypt the set of at least one of valid one-time passcodes;
• determine that the separate passcode matches a passcode in the set of at least one of valid one-time passcodes;
• and
• set the electronic lock in an unlocked state.
