Systems and methods for authenticating a subscriber identity module swap

A user device, comprising:

• one or more processors configured to:
• provide, to a provisioning device, a request for a subscriber identity module (SIM) swap that causes provisioning data to be provided to a first SIM card associated with the user device and from a second SIM card;
• generate a first token or key based on the request and based on one or more first user-provided SIM identifiers associated with the first SIM card,
• wherein the one or more first user-provided SIM identifiers include one or more of:
• a personal identification number (PIN),
• a password, or
• a biometric input;
• encrypt, using a public key provided by an application of the user device, the first token or key to generate a first encrypted token or key;
• provide, to the provisioning device, the first encrypted token or key and one or more user identifiers associated with a user of the user device,
• wherein the one or more user identifiers include one or more of:
• a telephone number associated with the user device,
• a username associated with the user, or
• an account number associated with the user;
• and
• selectively:
• receive the provisioning data from the provisioning device when the first encrypted token or key matches a second encrypted token or key generated based on one or more second user-provided SIM identifiers associated with a second SIM card, or
• receive, from the provisioning device, a message indicating that the user device cannot be provisioned, when the first encrypted token or key fails to match the second encrypted token or key.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a first user device, cause the first user device to:
• provide, to a provisioning device, a request for a subscriber identity module (SIM) swap that causes provisioning data to be provided to a first SIM card associated with the first user device and from a second SIM card associated with a second user device;
• generate a first key based on the request and based on one or more first user-provided SIM identifiers associated with the first SIM card,
• wherein the one or more first user-provided SIM identifiers include one or more of:
• a personal identification number (PIN),
• a password, or
• a biometric input;
• encrypt, using a public key provided by an application of the first user device, the first key to generate a first encrypted key;
• provide, to the provisioning device, the first encrypted key and one or more user identifiers associated with a user of the first user device;
• wherein the one or more user identifiers include one or more of:
• a telephone number associated with the first user device,
• a username associated with the user, or
• an account number associated with the user;
• and
• selectively:
• receive the provisioning data from the provisioning device when the first encrypted key matches a second encrypted key generated by the second user device based on one or more second user-provided SIM identifiers associated with a second SIM card of the second user device, or
• receive, from the provisioning device, a message indicating that the first user device cannot be provisioned, when the first encrypted key fails to match the second encrypted key.
