Occasionally, a user within your organization receives the following error message when they log in:
As a security precaution, this account has been locked due to too many failed attempts to log in.
Solution
To reactivate this account, work with an Analytics administrator within your organization in following these steps:
Note:
To aid in keeping your data secure and prevent unauthorized access, there are few circumstances where Adobe representatives can reset or provide passwords. Make sure that you complete all steps before opening an incident with Adobe Marketing Cloud Customer Care.
To regain access to marketing reports & analytics, try each of the following troubleshooting steps:
Clear the browsers cookies and cache: This step resolves about 90% of login issues.
Clearing cookies in Internet Explorer
Clearing cookies in Firefox
Clearing cookies in Chrome
Clearing cookies in Safari
Have a user with Admin permissions reset the account's password:
Log in to marketing reports & analytics with an account that has administrative rights.
Navigate to the Star Tab > Admin Tools > User Management.
Click the Users tab, then click the Edit link next to the user that is unable to log in.
Change the password to whatever you want, and select Require User To Change Password On Next Login.
Inform the user of the changed password.
If neither of the above work, locate how broad the issue is:
Can the user login if they try another log-in location, such as my.omniture.com, sc.omniture.com, sc2.omniture.com, or sitecatalyst.omniture.com?
Can the user login if they try a different browser?
Can the user login if they access Analytics from another computer?
Can the user login if they access the Internet from a different network, such as at home, via a mobile data connection, or elsewhere?
If the user can log in using any of the above, work with your organization's IT team to resolve the issue based on its breadth. If none of the above work, have one of your organization's supported users contact Customer Care. Make sure that they indicate that you have followed the above steps. An Adobe representative can then do additional troubleshooting on the backend to restore access to the affected login.
