Server side authentication

A non-transitory computer-readable medium storing instructions that, when executed, cause a first device to:

• send, to the second device based on a determination of an update event, an indication to update a first authentication string, wherein the indication comprises first a salt value and a second salt value;
• receive, from the second device, the username, the first authentication string, and a second authentication string, wherein the first authentication string is generated based on the first salt and the second authentication string is generated based on the second salt;
• and
• replace, based on a determination that the first authentication string matches the previously registered authentication string, the first authentication string with the second authentication string.

A second device comprising:

• one or more hardware processors;
• and
• physical memory storying instructions that, when executed by the one or more hardware processors, cause the second device to:
• receive, from a first device, an indication to update a first authentication string, wherein the indication comprises a first salt value and a second salt value;
• generate a second authentication string by applying a one-way hash function to the second salt value, a username, and a password;
• send, to the first device, the username, the first authentication string and the second authentication string, wherein the first authentication string is generated based on the first salt value, the username, and the password;
• and
• receive, from the first device and based on a determination that the first authentication string matches a previously registered authentication string, an acknowledgement that authentication information associated with a user of the first device has been updated.
