What Plaid is, and why your bank shows it

by Lee Schmidt

Published September 19, 2026

Plaid is a connection service that sits between your bank and the apps you authorize, so that an app can read your balances and transactions without ever handling your bank login. When a budgeting app asks to connect your bank, the window that opens is Plaid's, and the bank sees Plaid, not the app, as the party it is sharing data with. That is why your bank's own site lists Plaid among your connected apps, why the sign-in step sometimes happens on the bank's page and sometimes on Plaid's form, and why a connection can be ended from either end.

What Plaid does

Plaid does four things for a connection. It shows you a list of institutions and opens the sign-in for the one you choose. It asks you which accounts to share and records that choice. It delivers balances and transactions from those accounts to the app on a schedule, typically once a day. And it keeps the connection alive until the bank ends it or you do.

What the app receives is permission, in the form of a token that stands for your consent, and data, in the form of read-only balances and transactions. What the app never receives is your bank password. Plaid connects to over 12,000 banks, credit unions, card issuers, and brokerages this way, which is why the same window appears in so many different apps.

	Your bank's own page	Plaid's form for your bank
Where you type your password	On the bank's site, which hands you back when you're done	In the Plaid window
Who sees the password	The bank only	The bank, and Plaid, to establish and maintain the connection
What the app receives	Read-only data, through Plaid	Read-only data, through Plaid
Where the connection is listed	In the bank's connected-apps settings, and in the app	In the app
How to end it	From the bank's settings, or from the app	From the app, and a bank password change ends it too

Which route you get is up to your bank. Larger banks increasingly host the sign-in themselves, which is the stronger of the two because the password never leaves the bank. When Plaid shows its own form, Plaid receives your credentials under its own security program in order to keep the connection working. In both cases, the app itself never sees your credentials, and that is the reason a connection service exists at all.

What the app can and can't do

With a read-only connection, the app can see account names and types, current balances, and transactions, pending and posted, and it can ask Plaid for fresh data on a schedule. It cannot start a transfer, pay a bill, change your bank login, or see your password. An app that also moves money uses a separate permission for that, which a budgeting app doesn't hold. See Is it safe to connect your bank to a budgeting app? for what to check before you connect.

One connection, step by step

Step	What you see	What happens behind it
1. Choose your bank	A search box and a list of institutions	The list comes from Plaid, under the names institutions registered
2. The window opens	A Plaid-branded window naming the app	The app has asked Plaid for permission to read your accounts
3. Sign in	Your bank's page, or Plaid's form for your bank	The bank checks your credentials and any two-factor code
4. Choose accounts	A list of your accounts with checkboxes	Only the accounts you tick are shared; the rest stay invisible to the app
5. Done	The window closes and accounts appear in the app	Plaid gives the app a token for those accounts and starts delivering data
6. Every day after	Balances and transactions update	The app asks Plaid for new data, and Plaid asks the bank
7. Some months later	The connection needs reconnecting	The bank ended the session, on a schedule or after a password change

Step 4 is the one worth slowing down on. An account you don't tick is never seen by the app, so a business account or a child's savings account can stay out without any further setting.

Why your bank shows Plaid

Banks that host the sign-in list every service you have authorized on a connected-apps or third-party-access page, and the entry usually reads Plaid, sometimes with the app's name beside it. Some banks also email you when a third party first reads your account. Both are the bank doing its job, and both are the reliable place to see and revoke a connection from the bank's side, since removing a connection in the app drops the app's access but may leave the bank's listing in place until you remove it there too.

Common mistakes

Typing bank credentials anywhere but your bank's page or the Plaid window the app opened. A link in an email or a text, or a form inside the app itself, is the wrong place.
Sharing every account by habit. Untick the ones the app has no reason to see.
Never looking at the bank's connected-apps page, which lists services you authorized years ago and forgot.
Assuming disconnecting in the app removes the bank-side listing. Check the bank's page too.
Treating the bank's "third party accessed your account" email as an alarm when it arrives the day you connected. It is a receipt.

Common questions

Is Plaid safe? It is the standard way established apps connect to banks, and its design is the point: you sign in with the bank or with Plaid, never with the app, and the app gets read-only data. Plaid publishes its own privacy policy and end-user agreement, which say what it retains and for how long, and those are the documents to read rather than the app's.

Why does my bank name Plaid instead of the app? Because Plaid is the party your bank is talking to. The app is Plaid's customer, and some banks show the app's name beside Plaid's while others show only Plaid.

Can one Plaid connection serve several apps? No. Each app gets its own connection and its own token, and revoking one leaves the others untouched. Two apps connected to the same bank appear as two entries on the bank's connected-apps page.

What if my bank isn't in the list? Institution names in the search come from Plaid and don't always match the name on your card. Try the full legal name, the abbreviation, and the parent company; many credit unions and regional banks are listed under a parent brand. If it is genuinely absent, track the account by hand until it is supported.

How do I disconnect completely? Remove the connection in the app, which drops its token, and then remove Plaid from your bank's connected-apps page if your bank has one. Changing your bank password ends a connection made through Plaid's form as well, and the app will ask you to reconnect.

How Zypper handles this

Zypper connects through Plaid. From the connections settings you choose your bank, sign in inside the Plaid window, on your bank's own page when your bank offers it and on Plaid's form for that bank otherwise, and pick which accounts to share. In either case your bank credentials are never seen or stored by Zypper, which receives read-only financial data and cannot move money. Transactions and balances then sync automatically every day, you can refresh a connection at any time, and historical data fills in over the first minutes after connecting. If your bank doesn't appear in the search, the names come from Plaid and don't always match the name on your card, so try the full legal name, an abbreviation, or the parent company, and track the account by hand as a manual account in the meantime. There is no Zypper password to phish, since sign-in is by an emailed link or with Google. See Connecting your bank accounts and Bank not listed for the details, or get started with Zypper to connect your first account.
