On a computer with internet access, enter the web address https://scada.mervis.info, where the initial login screen will appear. The login credentials consist of a username and password.

• 1 – field for entering the username and password
• 2 – show / hide the section for entering multi-factor authentication details
• 3 – enable / disable saving login credentials for the next login (if saving is enabled and the login token is still valid, the user will be logged in automatically)
• 4 – login button
• 5 – link to switch to the mobile version of the site (see PWA)
• 6 – news page for scada.mervis.info (see News)

After checking the box for multi-factor authentication, an additional section for entering authentication details will appear. To use multi-factor authentication, the user must have the corresponding parameters configured in the Portal application (see Multifactor settings).

Two authentication methods are available:

• TOTP – login using a one-time password
• SMS – login using an SMS code

When using TOTP multi-factor authentication, it is necessary to enter the TOTP (one-time password) along with the username and password.

When using SMS multi-factor authentication, first click the button to send the SMS code, and then enter this code along with the username and password.
