Updating stored passwords

A method comprising:

• transmitting, by a device, a first form of a plain-text password to a server to establish a first connection to a network,
• the first form of the plain-text password being based on a first scheme;
• establishing, by the device, the first connection to the network based on transmitting the first form of the plain-text password,
• the first connection being established based on the server authenticating the device based on the first form of the plain-text password;
• transmitting, by the device, a second form of the plain-text password to the server to establish a second connection to the network,
• the second form of the plain-text password being based on a second scheme that is different from the first scheme, and
• the second form of the plain-text password being different from the first form of the plain-text password;
• determining, by the device, that an authentication associated with establishing the second connection to the network failed,
• the authentication being based on the second form of the plain-text password;
• establishing, by the device, a secure connection with the server, via a quarantine network, based on determining that the authentication failed;
• transmitting, by the device and via the secure connection, the plain-text password based on establishing the secure connection;
• and
• establishing, by the device, the second connection to the network based on transmitting the plain-text password,
• the second connection being established based on the server authenticating the device based on the plain-text password.

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

• one or more instructions which, when executed by one or more processors, cause the one or more processors to determine not to authenticate a device based on a first form of a password, received from the device, differing from a value associated with a second form of the password;
• one or more instructions which, when executed by the one or more processors, cause the one or more processors to establish, based on determining not to authenticate the device, a secure connection with the device via a quarantine network;
• one or more instructions which, when executed by the one or more processors, cause the one or more processors to receive, via the secure connection, a plain-text password from the device;
• one or more instructions which, when executed by the one or more processors, cause the one or more processors to compare a value derived from the plain-text password with the value associated with the second form of the password to determine whether the value derived from the plain-text password matches the value associated with the second form of the password;
• one or more instructions which, when executed by the one or more processors, cause the one or more processors to authenticate the device when the value derived from the plain-text password matches the value associated with the second form of the password;
• one or more instructions which, when executed by the one or more processors, cause the one or more processors to associate a third form of the password with the device when the value derived from the plain-text password matches the value associated with the second form of the password;
• one or more instructions which, when executed by the one or more processors, cause the one or more processors to receive, after authenticating the device, a subsequent first form of the password from the device;
• and
• one or more instructions which, when executed by the one or more processors, cause the one or more processors to authenticate the device using the first form of the password and the third form of the password.
