Limited-access functionality accessible at lock screen

A system, comprising:

• a user interface;
• and
• a processing device communicatively coupled to the user interface and configured to perform operations including:
• perform one or more authorized-access functionalities;
• perform at least one limited-access functionality, the at least one limited-access functionality being a subset of the plurality of authorized-access functionalities based at least partially on having access to less data stored in a memory than the one or more authorized-access functionalities;
• operate the user interface to display a lock screen, the lock screen configured to prevent unauthorized access to the one or more authorized-access functionalities and further configured to receive at least one user access credential to determine whether to provide access to the one or more authorized-access functionalities;
• receive a user input while the lock screen is displayed on the user interface;
• analyze the user input to determine whether the user input includes (1) at least one user access credential required to provide access to the one or more authorized-access functionalities;
• or (2) an invoking input that is configured to invoke the at least one limited-access functionality without requiring receipt of the at least one user access credential;
• and
• provide access to at least one of the one or more authorized-access functionalities or the at least one limited-access functionality based on the analysis of the user input.

• operate the user interface to receive an input while the lock screen is displayed;
• determine whether the input includes (1) at least one authorized-access credential required for accessing the one or more authorized-access functionalities, or (2) at least one limited-access input for performing at least one limited-access functionality;
• and
• based at least partially on the determination:
• if the input includes at least one authorized-access credential, attempt to verify the at least one authorized-access credential before providing access to the one or more authorized-access functionalities;
• and
• if the input includes at least one limited-access input for performing at least one limited-access functionality, provide the at least one limited-access input to the at least one limited-access functionality without requiring receipt of at least one authorized-access credential, the at least one limited-access functionality being at least one of (i) a subset of the one or more authorized-access functionalities, or (ii) providing less functionality than the one or more authorized-access functionalities based at least partially on having access to less data stored in the memory than the one or more authorized-access functionalities.
