Data replication across enterprise boundaries

A method comprising:

• receiving a request to update a server database from a first client database, the request comprising verification information of a user and a site ID of the first client database, wherein the verification information of the user relates to one-time passwords that are verified using at least one of the first client database, a second client database, or the server database, wherein the request is pushed from the first client database to the server database, wherein the first client database is within a first network;
• updating verification information stored in the server database based on the verification information from the first client database, wherein the server database is within a second network that is outside an enterprise boundary of the first network;
• receiving a request to update at least one of the first client database or the second client database by pulling the verification information from the server database to the at least one of the first client database or the second client database via an SSL tunnel;
• and
• sending the verification information to the at least one of the first client database or the second client database requesting the verification information from the server database,
• wherein at least one of the second database or the first database resolves which of a first verification information or a second verification information of the verification information to apply based on at least one of:
• unique data within the first verification information or the second verification information, timestamp data within the first verification information or the second verification information, or an authority assigned to the at least one of the second database or the first database with the first verification information or the second verification information.

A method comprising:

• receiving an identifier and a one-time password at a client;
• validating the one-time password at the client based on verification information stored in a client database, the verification information being associated with the identifier;
• performing an update operation to first verification information in the client database to indicate that the one-time password has been used, wherein the client database is within a first network;
• initiating an update to a server database from the client database by pushing first verification information and a site ID of the client database from the client database to the server database, the site ID comprising a geographic identifier to identify the client database, wherein the server database is within a second network that is outside an enterprise boundary of the first network;
• initiating an update to second verification information in the client database from the server database by pulling first verification information from the server database to the client database;
• and
• updating the second verification information in the client database based on first verification information pulled from the server database,
• wherein at least one of the server database or the client database resolves which of the first verification information or second verification information to apply based on at least one of:
• unique data within the first verification information or the second verification information, timestamp data within the first verification information or the second verification information, or an authority assigned to the at least one of the server database or the client database with the first verification information or the second verification information.
