Go to SE61.
Select General Text , Write ZLOGIN_SCREEN_INFO to Name . Click Change/Create.
You may use icons at the beginning of lines by specifying icon code for example @58@ .
Title lines (can be recognized by format keys starting with a 'U') are highlighted in the display.
Note that there is space on the logon screen for 16 lines for every 45 fixed-font characters or for approximately 60 proportional font characters.
Warning
If you modify screen SAPMSYST 0020 (in older releases), then note that you may only insert text elements.
Changes to the flow logic, for example, by inserting subscreen, force a change in program SAPMSYST.
SAP strongly recommends not changing the system program SAPMSYST because by doing so, serious problems may arise (for example, the dialog logon is generally no longer possible!)
