I’m thinking of the context first. What are we talking about here?
What I know so far is that there’s a login screen:
Login = an act of logging in to a computer, database, or system.
Screen = a flat panel or area on an electronic device such as a television, computer, or smartphone, on which images and data are displayed.
There are different types of ‘‘login’’/authentication: logon, login, sign-in. Are they under the same discussion?
Do we just consider a fully virtual environment or a combination with real device, physical actions also? like eye or hand scan, badge or card, keyboard code buttons; interaction between multiple devices or platforms? have a token to login to bank account, have a key/badge and a code to start/stop the house alarm, IoT + other platform/device…
What about the device type used? pc, mobile, tablet, ioT, token, medical device, other kinds of hardware…
OS dependent or or is it built/linked to the device?
Login screen type?: pin, command line, text-field, dots, fingerprint-reader, signature…
Application type?: hosted, server, web app, mobile app.
Online or offline login?
The list of questions can get pretty big…and in my opinion these can be considered tests also.
