Connect SimpleFIN
Accounts and transactions from every bank SimpleFIN Bridge covers — the finance default. You paste one token; the gateway claims it once and seals the durable access it converts to. Your bank logins live at the Bridge, never here.
1
Subscribe, and connect your banks — at the Bridge
Sign up at SimpleFIN Bridge and connect your banks there. That is where every bank login lives; Postern never sees one.
2
Copy the setup token
The Bridge hands you a setup token — a long base64 string. Copy the whole thing.
3
Paste into the Console
Console → Sources → SimpleFIN → paste → Connect. The token is single-use: the gateway claims it once and seals the durable access URL it converts to.
WHAT STANDS WHEN YOU FINISH
One finance connection carrying every bank the Bridge covers — accounts and transactions syncing on their own cadence, answered from the local cache in milliseconds by any agent you have granted finance. Disconnecting revokes only the sealed access; the Bridge subscription stays yours.
