Bypass Codes can be used as an alternative authentication method in the event users misplace their 2nd factor device. A bypass code is a user-specific 9 digit numerical code. When appended to a user’s password, it authenticates them without sending a request to their mobile or desktop app.
Each user can have up to 5 different codes. In order for a user to login using their bypass codes, the domain they are accessing must have bypass code authentication enabled.
A bypass code has 2 attributes:
Unlocking a Token
Each token has a set number of allowed unlock attempts. Any invalid unlock attempt, whether with or without a bypass code, is counted. If the number of invalid unlock attempts reaches the maximum for that domain (default 5) the token is revoked.
Once a token is unlocked, the number of invalid unlock attempts is reset to 0.
Professional, Business or Enterprise subscription required

There are two methods for creating bypass codes.
Manual bypass code creation is appropriate when you want to issue a small number of bypass codes. Since bypass codes are user-specific, each bypass code must be generated individually from the desired user’s page.
To manually create a bypass code:
You can use the powerful LoginTC REST API to programmatically add and manage bypass codes from your application or website. See Bypass Codes documentation for more details.Managing Bypass Codes
Bypass codes can be viewed and managed from two different locations on the LoginTC Admin Panel.
All of the organization’s bypass codes can be viewed and deleted from the Bypass Codes Index page. You can use the search tool to narrow down results.
Each user’s page has a table displaying their bypass codes. Bypass codes can be viewed, generated, and deleted from here
You can use the powerful LoginTC REST API to programmatically view, add, and delete bypass codes. See Bypass Codes documentation for more details.
Although a bypass code is user-specific, they can only be used to access domains that have bypass codes authentication enabled.
To enable or disable bypass codes for a domain:
When authenticating, a user enters their username normally. In the password field, they should should enter their password followed immediately by a comma and the bypass code.
Regular input (without bypass code) :
username: john.doe password: johnPassword
Input with bypass code :
username: john.doe password: johnPassword,123456789
If the bypass code is valid, the user will be authenticated without a request being sent to their 2nd factor device. If the bypass code is invalid, exhausted, or expired, the user’s request will be denied.
There must not be any spaces between the password, the comma, and the bypass code
For more examples see: Bypass CodeTroubleshooting
If your users are having difficulty authenticating with bypass codes, check the Logs page in the LoginTC RADIS Connector web interface:
If a user is trying to access a domain where bypass code authentication is not enabled, you will find the following error message within their authentication attempt:
2015-08-28 17:20:25,763 - DEBUG - Checking for bypass code 2015-08-28 17:20:25,800 - DEBUG - Bypass codes are not enabled for this domain 2015-08-28 17:20:25,800 - CRITICAL - Invalid credentials for user john.doe Exception: Invalid credentials for user john.doe
You can enable or disable bypass code authentication for a domain from the LoginTC Admin App. Click here for more information
If a bypass code is detected, you will find the following log messages associated with the user’s login attempt:
2015-08-28 17:17:51,268 - DEBUG - Checking for bypass code 2015-08-28 17:17:51,307 - DEBUG - Bypass codes enabled for this domain 2015-08-28 17:17:51,307 - DEBUG - Possible bypass code detected 2015-08-28 17:17:51,316 - DEBUG - Verifying bypass code for john.doe 2015-08-28 17:17:51,316 - DEBUG - Calling-Station-IP is null, not sending originating IP Address 2015-08-28 17:17:51,384 - CRITICAL - Invalid bypass code APIException: Invalid bypass code
In this case, the user may be attempting to use a bypass code that is either: – Expired – Exhausted – Incorrect
You can check the state of a user’s bypass code through the LoginTC Admin Panel, or programmatically through the Rest API. Click here for more information on managing bypass codes
If no bypass code is detected, you will find the following log messages associated with the user’s login attempt:
2015-08-24 16:15:38,435 - DEBUG - Checking for bypass code 2015-08-24 16:15:38,474 - DEBUG - Bypass codes enabled for this domain 2015-08-24 16:15:38,475 - DEBUG - No bypass code detected 2015-08-24 16:15:38,475 - CRITICAL - Invalid credentials for user john.doe Exception: Invalid credentials for user john.doe
In this case, the user is not correctly appending their bypass code to their password. Click here to review the format for entering bypass codes.
