Registration / Login


When you log in for the first time, you'll need to accept the invitation to buildagil. You can find instructions on how to do this in the following article: Accept the invitation


After accepting the invitation, buildagil can be opened in the browser via Https://app.buildagil.com or accessed via a project link. You can then log in using your email address and password.



After successfully logging in, you will be redirected to Project Home Page.


Troubleshooting


If the following troubleshooting steps do not resolve the issue, please feel free to contact Support.



If you're having trouble logging in, first try logging in to buildagil using your browser's incognito mode or private window.



Microsoft Edge: InPrivate Browsing
Google Chrome: Incognito Mode
Apple Safari: Private Browsing in Safari


Troubleshooting When a Username Is Missing

If, when accepting the invitation or attempting to log in, the message "This username may be incorrect. Make sure you entered the name correctly. Otherwise, please contact your administrator," it is most likely because you do not have a Microsoft account and cannot create one yourself. Please contact your IT support so they can create an account for you in your tenant, or contact our support team.



Troubleshooting When a User Cannot Be Found

If the error message "Unfortunately, 'email address' was not found in the 'buildagil.sharepoint.com' directory" or "Unfortunately, we cannot log you in" appears, there may be several possible causes.


The following sections describe ways to resolve this discrepancy:

  • The invitation from buildagil was not accepted
  • Changes to your Microsoft account
  • Incorrect Microsoft account used
  • No access to the project


The invitation from buildagil was not accepted
You cannot access the platform until you have accepted the invitation from buildagil. To accept the invitation, click the link in the invitation email from buildagil. The following article describes how to accept invitations: Accepting the Invitation


Changes to Your Microsoft Account
The following message may appear if changes have been made to your Microsoft account:
"Unfortunately, we cannot sign you in. AADSTS50020: The user account 'email@provider.com' from the identity provider 'provider.com' does not exist in the tenant 'buildagil' and cannot access the application '00000003-0000-0ffl-ce00-000000000000' (Office 365 SharePoint Online) in that tenant. The account must first be added as an external user in the tenant. Sign out and sign in again with a different Azure Active Directory user account."


In that case, please contact Support.



Incorrect Microsoft account used
If you use the wrong login for buildagil, you won't be able to access projects. Please note that the email address you use to receive notifications from buildagil is the one used for logging in.
The execution of logging in with the correct account is as follows:


First, click the link in the message to sign in with a different account.



After that, a message will appear indicating that the browser window can be closed. You can now open buildagil again to use a different account. You can then log in as usual.



If this does not help, you can also try deleting the cache in your web browser. For more information, see the following article: Clear the browser cache


No access to the project
If a link is forwarded from buildagil, it may reach someone who is not registered as a user of the project. So if you click on a link that does not come directly from buildagil and an error message appears, you most likely do not have access to the project. Please contact the person who sent you the link regarding access to the data.

Troubleshooting Sign-In Issues in the Mobile App with a Personal Microsoft Account

When attempting to sign in to the mobile app with a personal Microsoft account, the sign-in window takes an indefinite amount of time to load if you sign in using "face recognition, fingerprint, PIN, or security key." A sign-in dialog does not appear.



This is because this sign-in method is not supported. As a result, the page does not load in the app. Instead, you can switch to the password or authenticator method. If the options "Use my password" or "Approve the request using my Microsoft app" do not appear during login, it may help to remove the "Use master key" method from your Microsoft account settings. For more information, see the following article: Removing a sign-in verification method.


Troubleshooting Queries on the Primary Key

When you try to sign in with your Microsoft account, the following dialog box may appear: "Select where you want to save your master key." If you select “iPhone, iPad, or Android device,” a QR code will appear that you can scan with your phone’s camera to set up the desired sign-in method. If you do not want to complete the setup at this time, you can close the window by clicking “Cancel” to return to the sign-in process.



Troubleshooting Login Issues in the iOS App

When signing in to the iOS app, the following message may appear: “You cannot sign in with your account. This is due to the sign-in process set by your organization. Please contact our support team (support@buildagil.com).” This message appears if your organization uses ADFS-based sign-in (company-specific sign-in page) for Microsoft. However, due to technical limitations, this type of sign-in is no longer supported in the iOS app. In this case, you must use buildagil via a web browser as long as ADFS-based sign-in is active. Alternatively, your organization can switch from ADFS to cloud-based authentication (e.g., the standard Microsoft sign-in). Once this transition is complete, you will be able to use the iOS app again.



Troubleshooting Recurring Login Prompts

You may notice that the login prompt appears more frequently than usual. To resolve this, you can allow pop-ups and redirects for buildagil.



In the desktop app, this can be configured directly through the options in the app info section.



In the browser, the setting appears in the search bar when the sign-in dialog box appears, and can be changed there. Alternatively, "buildagil.sharepoint.com" can be allowed in the browser settings under "Pop-ups and Redirects."
