Encryption methods and apparatus

At least one non-transitory computer-readable storage medium configured to store instructions that, in response to being executed by at least one processor included in a computing device, cause the computing device to:

• receive a first indication to update a current password at a first client device with a new password, wherein the first client device is associated with a user account;
• provide a first encrypted key that is stored at the computing device to the first client device, wherein the first client device decrypts the first encrypted key by using the current password;
• receive, from the first client device, a second encrypted key that includes the new password;
• store the second encrypted key;
• and
• in response to receiving a second indication from a second client device to update the current password at the second client device with the new password, wherein the second client device is associated with the user account:
• provide the second encrypted key to the second client device, wherein the second client device decrypts the second encrypted key with the new password that was entered at the second client device.

A method for updating a password, the method comprising, at a client device associated with a user account:

• receiving a current password;
• generating a first key by encrypting the current password with a primary random key;
• sending the first key to a server device;
• and
• in response to receiving a new password for updating the current password at the client device:
• generating a second key by encrypting the new password with the primary random key, and
• storing the second key at the client device.
