ORBI RBS750 are working on my home network but the Orbi App now want's my "admin" login password

Netgear's Orbi product has a number of sets of credentials:

• The WiFi credentials: after selecting the desired WiFi Service Set IDentifier (SSID), the user supplies the correct password to gain access.
• The router web administration credentials: user name "admin" (which cannot be changed) and a password that was created during the initial setup (and many users immediately forget).
• The Orbi 'app' credentials, which are usually the same as the Netgear login (an email address plus a password).

I have observed a number of times when the Orbi app is updated, that it will demand my admin credentials and helpfully supply suggestions that I have not used in years.  Or, it will seem to forget the Netgear login that has worked for months and suggest that I use "admin" and a password - which of course are not accepted.

So, if the Orbi 'app' truly wants the web admin password, that is indeed what it wants.  If it is simply being stupid, then maybe it wants the Netgear login.

p.s. When the Orbi is set up  initially, or is Factory Reset, then the web admin credentials are "admin" and "password", and  during the setup users are badgered into changing the password to something that meets more secure requirements. (8 or more characters, upper and lower case, number, etc. etc.)
