Is there any timeout for the info in the "password" field on iOS?

Question

iOS

The crux of the matter is that if, after entering the password, the program generated an error connecting to the server (the Internet is gone or the desired server is unavailable at that moment) and if the program is not closed, but simply minimized (as is usually the case on iOS), then the password remains entered . And when you resume access to the Internet, or when you restore the availability of the server, you can safely log in, because the password has already been entered.
Is it possible to reset the password entry form in case of an unsuccessful attempt to connect to the server or after a short period of program inactivity? Or is it fundamentally impossible on iOS?
