Accessing the System

You need a web browser, enter https://is.slu.cz/ and click to “Login”.

To access authenticated services, you need to know your login details from the Central Register of Persons SU.

In case of problems, System administrators will help you.

To log out of the System, click on the log-out icon situated in the upper right-hand corner.

To log out of the IS SU Notification mobile app, the user must remove the device from the paired devices:

Without a check mark, you will only log out on the device you are currently clicking on. When checked, you will be immediately logged out of all devices on which you are currently logged in. If you access the system via a small screen device (typically a mobile phone), the „log out from other computers too“ option is not displayed and the system immediately logs off the user only on the current device. To log out from other computers as well, select:

Login in IS SU is always valid for 4 days after the last operation (after the last click). You use the „log out from other computers too“ option when you realize that you forgot to log out on a device to which you no longer have access.

To log in to the system, the user must know their učo (university identification number) and have a valid password assigned.

When entering your password, make sure to check the following:

• Whether the correct keyboard layout is selected on your computer or laptop. A common issue is entering incorrect characters when typing on a switched English keyboard layout. On many systems, the keyboard layout can be changed in the bottom right corner of the screen.
• Whether digits and letters are not being confused: e.g., number 1 vs lowercase letter l, or 0 (zero) vs O (uppercase o), or lowercase letter l vs I (uppercase I).
• Whether CapsLock on keyboard is off.
• Whether the učo has been entered correctly.

Also, make sure that cookies are enabled in your browser. By default, all major browsers have cookies enabled, but some security extensions or incorrect browser settings may block essential cookies required for the system to function properly.

If you still can’t log in and are sure that both your učo and password are correct, it is most likely that you have a different password stored in the system. In that case, you need to restore your access. For the list of access rights administrators assigned to individual faculties, please go to:

We strongly recommend against saving your password in your browser (i.e., using the “Remember password” option after logging in). If you enable this option, anyone with access to your device may be able to log into the IS SU system under your identity while you are away.

If you ignore the warning displayed on the IS SU login page and still choose to save your password in the browser, you accept full personal responsibility for any potential misuse of your login credentials.

IS SU users can voluntarily provide their private phone number and personal email address in the system in case of emergency situations, such as when a password is compromised through a phishing email. If such a situation occurs, authorized personnel will be able to contact the user using this information and help resolve the issue.

Users can enter their emergency contact details in the following application:

If the error occurs for the first time, repeat after a few minutes to see if the problem persists.

If the problem persists, follow these steps:

1. Find out if you have Internet access. Try familiar servers such as https://google.com/, https://seznam.cz/. If they don't work, check your internet connection.
2. Find out if the unauthenticated IS SU title page https://is.slu.cz. is displayed. If it does not appear, contact is@slu.cz. Fill in the following information in the e-mail:
   • What exactly error message does your browser display, or what information does the browser load the page, but the loading does not end within a few minutes.
   • From which IPv4 address do you access the MU IS (you can find out, for example, at https://whatismyip.com).
   • Which of the following pages works for you and which don't:
     • https://theses.cz
     • https://www.fi.muni.cz
     • https://www.muni.cz
     • https://www.cesnet.cz
   • How long and possibly how often do you observe the problem with connecting to the IS SU from this place.
3. Find out if you see an authenticated and secure page https://is.slu.cz/auth/, resp. if the system prompts you to log in to the IS SU (islogin.cz domain). You log in by entering your account and password. Do not use bookmarks in your browser in this step, type the address https://is.slu.cz/auth/ directly into the browser's address bar. If it doesn't appear, try clearing your browser's password and trying to clear your browser's cache. Contact your computer administrator to resolve these issues.

Cookies are probably not enabled in your browser. By default, all major browsers have the necessary cookies enabled. However, some security extensions or incorrect browser configuration may block essential cookies required for the system to function properly. You can enable cookies by following the instructions specific to your browser.

Browsers remember your login to IS SU for up to 4 days since your last activity, which allows for smoother use of the system without the need to log in repeatedly. If you want to prevent this, always log out after finishing your work in the system.

The login remains valid for up to 4 days from the last performed action.

temporarily
