Please help me to confirm the proper use of onto in this partial sentence. Thanks very much!

I would not use "onto."
Thank you so much. And if I may inquire...what is the grammar reasoning behind your choosing "on to" vs. "onto".

Appreciate the clarification and love this site.

The noun/adjective is "logon" - Enter your logon/logon information.

The verb is "log on." After you log on, you can...

The phrasal verb it log ON, not log ONTO.
If I may (from Am Heitage Dict):

•In constructions where on is an adverb attached to a verb, it should not be joined with to to form the single word onto: move on to (not onto) new subjects; hold on to (not onto) our gains.

It is an adverb because it can stand alone with its verb: I tried to log on, but could not.

Hi there,

Please could somebody confirm whether below is correct:

The study goes on to say that...

Bob goes on to say that...

Thanks, very much appreciated
