Manual Login Testing Needed

I want a clear-cut, manual verification of the login page on my website. The scope is intentionally narrow so you can go deep rather than wide: test the classic email-and-password flow only, on a desktop computer, using Google Chrome as the single target browser. Your job is to design well-structured test cases, execute them, capture every actual result, and flag anything that deviates from the expected behaviour. That includes checking how the page handles valid credentials, invalid usernames or passwords, and empty form submissions, plus confirming that success and error messages render correctly. Please document everything tidily and attach full-screen screenshots for any defect you discover. I need to be able to follow your steps and reproduce issues without guesswork. Deliverables • Excel file with all test cases and expected results • Test execution report showing pass/fail status for each case • Bug report (only if defects are found), complete with steps, observed result, expected result, and screenshots • Final testing summary outlining overall quality, coverage achieved, and any open issues I value concise, well-organised documentation over bulk, so focus on clarity and accuracy.
