you can check this your self also. Go to SE80... click on "Repository Information System"... Open the drop down "Program Library" under Object section... Double Click on the selection "Function Module".

Search for the FMs available for different types of Logon with search term "Logon".

For e.g., few are provided here:

SUSF (Function Group)

SUSR_LOGON_USER_EXIT

SUU1 (Function Group)

SUSR_USER_LOGONDATA_GET

SUSR_USER_LOGONDATA_PUT

SUSR_USER_LOGONDATA_SETCHANGED

There's only an user-exit (SUSR0001) which is invoked after a successful SAPGUI logon.

Notice: there is no way to implement own login modules or to execute own coding prior / during authentication.
