The login will only show if the router is not bound to TP-Link ID. In the screenshots you provided initially in the notes part it will elude to that. So if you were to unbind your Archer A20 you would see below:

With respect to remote access you do not need to enable Remote Management, that would be if you want to access the router using the IP address. With the TP-Link Cloud, once you bind the router it should now appear as cloud in Tether. How is the router showing up in your Tether app?

Thanks, you might have solved ALL the problems?

As for the User's Guide, I now see how to do those 2. Since I did change the password to the Cloud P/W, I suspect I did see that, and I probably setup the recover P/W as well. I guess just a shortcoming in the User's Guide to let you know how to do that more clearly, especially if one wants to change the p/w after they linked the account. I didn't make the connection to changing the router password to changing the Cloud password. I thought they were 2 different passwords.

In Tether, it seems it was showing as a Local Device. Now shows as a Cloud Device. Possible I never logged it? Possible I got Logged out? I did have to re-boot the phone recently. No 'keep me logged in'? Yes, even on my Home Wifi I see it as a Cloud Device. Will test on a HOTSPOT tomorrow.

Thanks for the clarification.

I actually answered this in https://community.tp-link.com/us/home/forum/topic/173192?replyId=363948

Seems Tether holds on to some old IP Address. It happened when I used Tether on my home wifi and next on a hotspot out of my home. It got confused.

@IrvSp 

I used the screenshots you provided in the referenced thread to see if I can confirm what you think happened or another explanation.

@Tony ,

Thanks,

Went to a Dr's office and was on another Public Hotspot and I had no problems?

By the way, both of these 2 hotspots are from my ISP as well. In both cases I did leave the house and the phone switched automatically to Cell and then the Hotspots when in range.

Very strange, it is really hard to pin down?

@Tony ,

In trying to verify some of the problems on Tether, I discovered another oddity.

I'm sitting at my PC and decide to check if my phone has switched over to Wifi, It has, so I tried Tether and it worked? OK, I just put the phone down.

In reading the other thread about the "-" I decided to use Firefox to look at the connected clients to see how many were like that. When I entered the UID and PW I was prompted that another device was controlling the router. Great, nice to know, and I confirmed I wanted to take control. So I entered...

So now I pick up the phone. Yup it isn't connected, the top screen with the Cloud device shown. Hmm, let me try accessing. Got in, no problem, no warning I was knocking someone else off, and yes, the PC was out of control...

I'd think that 'warning' should have been on Tether as well probably?

I hope you aren't sick of hearing from me....

@IrvSp 

I laughed reading the last line. No, definately not.

What you brought up about the Tether, I can see what you are referring to. The app makes no mention like the web browser does.

Thank you for bringing this to our attention. 

@IrvSp 

The feedback I received was the Tether was doing as designed so you will only get a message of a login conflict when on a browser, not the app.

@Tony 

Thanks for checking. Surprising, but it is what it is...

Thanks again.
