Fix · Sign-in and accounts

The sign-in link (magic link) says expired or does not log me in

Not checked against the vendor's current screens

What you may see

I click the email link and land on the login page again
Links work in one browser and not when the email app opens them

Most likely cause

The link works once, for a short time, and in the same browser or flow that asked for it; email apps may open it in a different built-in browser or pre-open it.

Check first (about two minutes)

Does it work if you copy the link into the same browser where you asked for it?

The fix prompt

What you type here never leaves your browser. The search runs on this page, and nothing is sent to a server or to an AI.

The exact error or what you see

What you did before it happened

Kept only in this browser, on this device. Keys and passwords are removed before anything is saved.

Prompt language

You are a careful senior engineer who knows sign-in, sessions and user accounts, and explains them to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

Menu and button names change over time. If you cannot find a button or page I mention, say so and tell me what to look for instead of guessing.

THE PROBLEM
The sign-in link (magic link) says expired or does not log me in

THE EXACT ERROR OR WHAT I SEE
[paste the exact error here]

WHAT I DID BEFORE IT HAPPENED
[write in a few words what you did before it happened]

MOST LIKELY CAUSE
The link works once, for a short time, and in the same browser or flow that asked for it; email apps may open it in a different built-in browser or pre-open it.

DO THESE STEPS, IN THIS ORDER
1. Check the flow that creates the session from the link and which browser/device it expects.
2. Offer a one-time code that the user types as an alternative, which avoids the browser change.
3. Show a friendly message and a "send a new link" button when a link has expired.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- Login works from the email on iPhone and Android mail apps or via the code.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not lengthen the validity to days.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

After you tried it, did it work?

Steps

Check the flow that creates the session from the link and which browser/device it expects.
Offer a one-time code that the user types as an alternative, which avoids the browser change.
