Monitoring strength of passwords
A method is used in monitoring strength of passwords. A a request is received from a user to use a user password. A password score is determined for the user password. The password score indicates quality of the user password. Based on the password score, the strength of the user password is evaluated in a privacy preserving manner. The privacy preserving manner indicates avoiding storing information regarding the user password after strength of the user password has been evaluated.
1. A method of controlling access to resources by monitoring a strength of a password, the method comprising:
receiving a first request from a user to access a first resource;
receiving, after receiving the first request, a user password from the user as a condition of determining whether access to the first resource should be granted;
successfully authenticating the received user password, wherein the user password has been authenticated at least one additional time in the past;
determining a password score for the user password after successfully authenticating the user password, wherein the password score indicates quality of the user password;
based on the determined password score, evaluating strength of the user password in a privacy preserving manner, wherein the privacy preserving manner indicates avoiding storing information in a memory or a processor regarding the user password after the strength of the user password has been evaluated;
denying access to the first resource because the strength of the user password does not exceed a first threshold score;
receiving a second request from the user to access a second resource;
receiving the user password from the user as a condition of determining whether access to the second resource should be granted;
successfully authenticating the user password in connection with the second request;
determining a second password score for the user password after successfully authenticating the user password, wherein the second password score indicates quality of the user password;
based on the second password score, evaluating strength of the user password; and
granting access to the second resource because the second password score exceeds a second threshold score.
2. The method of claim 1 , wherein the second password score is different than the first password score.
3. The method of claim 1 , wherein a client module resides within a web application, on a mobile device, or a computing device.
4. The method of claim 1 , wherein determining the password score and evaluation of strength of the user password is performed by a password scorer module.
5. The method of claim 1 , wherein a client module and a password scorer module reside within a single device.
6. The method of claim 5 , wherein the user password is sent to a password scorer module over a secure connection.
7. The method of claim 1 , wherein strength of the user password changes overtime.
8. The method of claim 1 , further comprising prohibiting access to a network if the threshold score is below a threshold level.
9. A system for controlling access to resources by monitoring a strength of a password, the system comprising a memory and a processor configured to:
receive a first request from a user to access a first resource;
receive, after receiving the first request, a user password from the user as a condition of determining whether access to the first resource should be granted;
successfully authenticate the received user password, wherein the user password has been authenticated at least one additional time in the past;
determine a password score for the user password after successfully authenticating the user password, wherein the password score indicates quality of the user password;
based on the determined password score, evaluate strength of the user password in a privacy preserving manner, wherein the privacy preserving manner indicates avoiding storing information regarding the user password in the memory or the processor after strength of the user password has been evaluated;
deny access to the first resource because the strength of the user password does not exceed a first threshold score;
receive a second request from the user to access a second resource;
receive the user password from the user as a condition of determining whether access to the second resource should be granted;
successfully authenticate the user password in connection with the second request;
determine a second password score for the user password after successfully authenticating the user password, wherein the second password score indicates quality of the user password;
based on the second password score, evaluate strength of the user password; and
grant access to the second resource because the second password score exceeds a second threshold score.
10. The system of claim 9 , wherein the second password score is different than the first password score.
11. The system of claim 9 , wherein a client module resides within a web application, on a mobile device, or a computing device.
12. The system of claim 9 , wherein determining the password score and evaluation of strength of the user password is performed by a password scorer module.
13. The system of claim 9 , wherein a client module and a password scorer module reside within a single device.
14. The system of claim 13 , wherein the user password is sent to a password scorer module over a secure connection.
15. The system of claim 9 , wherein strength of the user password changes over time.
16. The system of claim 9 , further comprising prohibiting access to a network if the score is below a threshold level.
17. A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing device causes the at least one processing device to:
receive a first request from a user to access a first resource;
receive, after receiving the first request, a user password from the user as a condition of determining whether access to the first resource should be granted;
successfully authenticate the received user password wherein the user password has been authenticated at least one additional time in the past;
determine a password score for the user password after successfully authenticating the user password, wherein the password score indicates quality of the user password;
based on the determined password score, evaluate strength of the user password in a privacy preserving manner, wherein the privacy preserving manner indicates avoiding storing information in the non-transitory, processor readable storage medium or a memory coupled thereto regarding the user password after strength of the user password has been evaluated;
deny access to the first resource because the strength of the user password does not exceed a first threshold score;
receive a second request from the user to access a second resource;
receive the user password from the user as a condition of determining whether access to the second resource should be granted;
successfully authenticate the user password in connection with the second request;
determine a second password score for the user password after successfully authenticating the user password, wherein the second password score indicates quality of the user password;
based on the second password score, evaluate strength of the user password; and
grant access to the second resource because the second password score exceeds a second threshold score.
