GPAL Fluent: High-level fluent C# API

//SaveTo(grid) appends a [Username, Password] row regardless of ServiceType, so the same FillInFrom step works whether the credentials came directly from code, a password manager vault, or were built as a master login for WithCredentials.

// Direct username/password - no password manager involved

var grid = GPAL.Grid.ToGPALObject();

GPAL.CredentialsFor(CredentialServiceType.None)

.WithUsername("admin@example.com")

.WithPassword("s3cret")

.SaveTo(grid);

// Use the grid to fill in a login form

GPAL.Browser

.GoTo("https://example.com/login")

.WithSelector("#username")

.WithSelector("#password")

.FillInFrom(grid)

.WithSelector("#login")

.LeftClick();
