Any league. Read-only. Here's exactly how.
Fantasy Memo reads your league; it never writes to it. Yahoo takes a league id. ESPN takes two cookies from your browser once — and this page shows you precisely where they are. Anything else takes a pasted roster or a screenshot. Choose Hockey on the connect page first, or start from hockey.fantasymemo.com and it is chosen for you.
Public — anyone with the link can see the league without signing in; the id alone connects it. Private — members only; two cookies from your signed-in Yahoo tab let it be read, or you paste your roster instead. Most leagues are private; it is Yahoo's default. Not sure? The app offers a thirty-second test: open the league address in a private window without signing in — rosters visible means public, a sign-in prompt means private.
Public league — the id alone
- 1Choose Public. The league id field appears.
- 2The id is the number at the end of your league's address:
hockey.fantasysports.yahoo.com/hockey/123456. Enter it, press Find league, pick your team. Done — every roster in the league is read, so the league read, the matchup and trades all work.
Private league — cookies first, then the id
- 1Choose Private. Two boxes appear, labelled
YandT— the league id field waits until they are filled. - 2In a signed-in Yahoo tab open developer tools — ⌥+⌘+Ihold all three down at the same time on a Mac, F12 on Windows — then Application (Chrome/Edge) or Storage (Safari/Firefox) → Cookies →
yahoo.com. - 3Copy the value of the cookie named
Y, paste it into the Y box; then copyTand paste it into the T box — one at a time, the clipboard holds one thing. Save cookies. - 4The league id field appears. Enter the id, Find league, pick your team.
Rather not copy cookies? Paste my roster instead on the same panel — copy your roster or upload a screenshot — gets you everything about your own team, without the league-wide read or trades. Our official Yahoo sign-in is submitted for Yahoo's review; when approved it replaces the cookies.
Paste or screenshot — any league at all
- 1In the app choose Any other league (or Paste my roster instead on Yahoo). Give the league a name, set the number of teams, the scoring and the starting slots.
- 2Paste your roster, one player per line — or give it a screenshot of your roster page and the names are read for you. The screenshot box takes an image three ways: drag and drop it onto the box, click to choose a file, or paste an image from the clipboard (on a Mac, ⌃⌘⇧4 puts a screenshot straight on the clipboard). Slot labels, “Edm - C”, injury tags and projections can come along; names are what matter.
- 3Optional, for the matchup: add this week's opponent. Paste their roster, or drop a screenshot of their team page onto the opponent's own box — a screenshot of the matchup page works for both sides at once, and their side is picked out.
- 4Press Check the names: you see exactly what matched and what did not, and can fix a spelling before anything is saved. Then Connect this league.
- 5After a move, Update roster on the Roster page — paste or screenshot again, yours and the new week's opponent. Got the scoring, slots or format wrong? League settings, on the Roster page and beside each league on the connect page.
ESPN does not offer fantasy apps an official way to connect. Every third-party tool that reads an ESPN league — ours included — has to do it the way you are about to, by borrowing your own signed-in session. We know it is a chore the first time, and we are sorry you have to do it. It is a one-time job of about a minute on a computer, this page walks you through every click, and the moment ESPN opens a proper door we will use it. Until then, this is how it works for us and for everyone else.
Is your league public or private?
A public league can be viewed by anyone with the link, signed in or not — it connects with just the league ID. A private league can only be seen by its members — it needs the two cookies below. Most ESPN leagues are private; it is the default when a league is created.

It reads what kind of league it is, and scores like it.
Scoring and lineup mode are read from the platform and set by hand for a pasted league (League settings).
Yahoo's defaults, 12-cat or your own set, most-categories or each-category. Every category projected for the week from both sides' starters times their games and starts.
No opponent: your standing in every category against the whole league, with the gap up and down, so a move is valued by the places it buys.
Your points-per-stat on the same per-game lines. ESPN's defaults are read from the league; the board and the memo value goalies the way your league does.
Yahoo and ESPN set nightly by default; some leagues lock the week. Streams, the checks and the Daily Memo all follow from which it is.
Keepers are never proposed as drops; IR, IR+ and LTIR players stay out of every lineup.
Questions
Why isn't Sleeper listed?
Sleeper does not host fantasy hockey leagues. Its hockey data (players, schedule, last season's lines) is part of what the app reads; the leagues themselves live on Yahoo, ESPN and the platforms you paste from.
Is it safe to paste my ESPN cookies?
The two cookies are your own signed-in session, the same thing your browser sends ESPN on every page. Fantasy Memo stores them encrypted (AES-256, keyed on the server), uses them only to read your league, and never writes to it. Sign out of ESPN everywhere and they stop working; disconnect the league in the app and they are deleted.
My league uses categories. Does the app read which ones?
From Yahoo, yes — the stat categories and whether it is H2H or roto. ESPN's categories or points-per-stat are read from the scoring settings. A pasted league takes a preset (Yahoo defaults, 12-cat, ESPN points) you can edit in League settings.
Daily or weekly lineups — does it matter?
It changes everything downstream, so it is read carefully. A daily league gets a lineup per game night, a nightly check, and the Daily Memo add-on if you want the note written. A weekly league gets one lineup, checks on Wednesday and Friday, and streams phrased for next week once this one is locked.
Does it ever change anything in my league?
No, on any platform. Every connection is read-only. It cannot set a lineup, make a claim or send a trade — it tells you what to do and you do it.
Can I connect from my phone?
Yahoo (by pasting your roster), yes — and any other platform the same way. ESPN needs a desktop browser once, to copy the cookies; after that the app works anywhere.
