This article gathers the most common reasons why you might not be able to access the Buk platform and what you can do to fix it on your own, without needing to contact support.
User not created
The first thing is to understand the difference between auserand acollaborator. In Buk, auseris the one who can log in to the platform and has the access credentials. In contrast, acollaboratoris the entity associated with the job and has a collaborator record.
Although they can be linked, this is not always the case: a user may not have an associated collaborator,and a collaborator may not have a user created to log in to the platform. This usually happens when a collaborator is registered but no user is created for them.
To see how to create users, you can review the articleUsers - Configuration and Use Manual.If you already created it, review the following point:
Is this your first time using Buk?
To log in for the first time, you must activate your account. To do so, you will receive an activation email sent by your company when the user is created. If you can't find it, contact your Human Resources team for assistance.

💡Note:You can view the article“How to activate my Buk account?”for more details.
You won't be able to reset your password if you haven't activated your account yet.
Account locked due to failed attempts
Another common reason you can't log in is that your account may have been locked. An accountis automatically locked after 5 failed attemptsat sign-in in any of the following cases:
Entering the incorrect password.
Entering the phone number or the code received by SMS incorrectly.
Entering the two-factor authentication code incorrectly (if it is enabled in your company).
ℹ️Note:This counter resets automatically every 24 hours, but you can try to unlock your account earlier, as described below.
How can you unlock your account?
-
Reset the password via email or SMS.
Click on “Forgot your password?” on the sign-in screen. You can choose between two methods:-
By email:Click on “Forgot your password?” on the sign-in screen. Enter your email and complete the captcha. Then select the password reset method.
Didn't receive the email?
Check your inbox, spam folder, or junk mail.
Verify that you entered your email address correctly.
In some cases, the message doesn't arrive because the account hasn't been created or activated yet.
If the problem persists, you can try resetting the password using the SMS option.
💡Note:You can view the article“How to reset my password?”for more details.
2. By SMS:Click on “Forgot your password?”, enter your email and complete the captcha. Then select the option“Text message”(if you don't have a phone registered on your profile, the flow will automatically take you through the email one), enter the last 4 digits of your registered number and type the code you will receive by text to set a new password.
Didn't receive the SMS?
Wait a few minutes and try again. Sometimes the sending service may experience temporary interruptions.
If the code still doesn't arrive, your number may be registered incorrectly. In that case, contact an administrator so they can check it on your collaborator record and update it if necessary.
As a reminder: make sure you have yourpersonal phoneupdated in“My Profile”so that this option works correctly in the future.

Email for blocked access attempt.
If you try to sign in while your account is locked, an email will be automatically sent with a link to reset your password (valid for 2 hours). After completing the process, your account will be unlocked. Check your inbox or spam folder.
Contact an administrator.
We recommend first trying the previous methods, as they can be much faster.
The administrator can go to the sectionUsers and Profiles, locate the user under the"Blocked"tab and select the option"Reset password". This will send an email with a link for the user to create a new password. The account will be unlocked once the user resets their password.
-
Wait 24 hours.
After that period, all accounts are unlocked automatically without needing to do anything, and you can try signing in to your account again.
Remember that you can also change your password from within the platform.
Click the buttonMy account(top right) and select the optionReset my password.
⚠️ Important: This option is available only for thosedo not have SSO active.
If your organization uses single sign-on (SSO), passwords are managed externally and this option is not shown in the menu.
