Password authentication
First Claim
1. A method, comprising:
- receiving a credential to access a computer system, the credential comprising a user password and a one-time password (OTP);
authenticating, by a processor, the user password using a cached password;
when the computer system is unable to access an authentication server and unable to authenticate the OTP using the authentication server, storing the OTP and the user password in a memory of the computer system and granting, by the processor, a user a first level of access to the computer system, wherein the first level of access is granted in view of the authentication, by the processor, of the user password using the cached password and without authenticating the OTP;
checking whether the computer system is able to access the authentication server; and
when the computer system is able to access the authentication server, authenticating the stored OTP using the authentication server and granting, by the processor, the user a second level of access to the computer system, the second level of access being different than the first level of access, and wherein the second level of access grants the user an access ticket to access one or more of network resources.

Abstract
A user credential comprising a user password and a one-time password (OTP) may be provided to access a computing system. The user password is authenticated and the network connection status of the computing system is determined. If the computing system is offline, the user password and the OTP are stored in memory and the user is granted a first level of access to the computing system. Upon detecting that the network connection status of the computing system has changed to online, the user password and the OTP are provided to an authentication server for authentication. If the authentication of the user password and the OTP is successful, the user is granted a second level of access to the computing system, the second level of access being higher than the first level of access.

8. An apparatus comprising:
-
a memory to store a plurality of one-time passwords; and a processor, operatively coupled to the memory, to; receive a credential to access a computer system, the credential comprising a user password and a one-time password (OTP); authenticate the user password using a cached password; when the computer system is unable to access an authentication server and unable to authenticate the OTP using the authentication server, store the OTP and the user password in a memory of the computer system and grant a user a first level of access to the computer system, wherein the first level of access is granted in view of the authentication, by the processor, of the user password using the cached password and without authenticating the OTP; check whether the computer system is able to access the authentication server; and when the computer system is able to access the authentication server, authenticating the stored OTP using the authentication server and granting the user a second level of access to the computer system, the second level of access being different than the first level of access, and wherein the second level of access grants the user an access ticket to access one or more of network resources. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory machine-readable storage medium including data that, when accessed by a processor, cause the processor to:
-
receive, by the processor, a credential to access a computer system, the credential comprising a user password and a one-time password (OTP); authenticate the user password using a cached password; when the computer system is unable to access an authentication server and unable to authenticate the OTP using the authentication server, store the OTP and the user password in a memory of the computer system and granting, by the processor, a user a first level of access to the computer system, wherein the first level of access is granted in view of the authentication, by the processor, of the user password using the cached password and without authenticating the OTP; check whether the computer system is able to access the authentication server; and when the computer system is able to access the authentication server, authenticate the stored OTP and the user password using the authentication server and granting, by the processor, the user a second level of access to the computer system, the second level of access being different than the first level of access, and wherein the second level of access grants the user an access ticket to access one or more of network resources. - View Dependent Claims (16, 17, 18, 19, 20)
