How to change Password Temporarily?

[DotCom2]

I am going to be having surgery soon so I want to give access to my daughter in case I am unable to access my computer and/or iPhone. Both my iphone and computer have the same 4 digit passcode. I know I can change my passcode, but what I want to know is, if I change it to something just temporarily, can I change it back to the original passcode I had? I have had experiences with changing passwords and then it won't let you change it back to the original one. Is this doable on iPhones/Macs?
Please advise only if you have actually done this please, and no you "should be able to" responses please. Just people who have actually done this successfully.
Thank you!

Yes. I just tested this on my iPad to be absolutely certain. Changed the passcode, then changed it right back. There is no error or warning message, it just works as expected.

Thank you so much for doing that, ryanarrr.
