1. Create a BudgetSyncer account and connect YNAB with OAuth.
2. Start a 7-day free trial on the website or App Store — required before connecting a bank.
3. Choose your country and bank. Complete the bank’s consent screen (SCA as your bank requires). BudgetSyncer does not store bank passwords.
4. On the mapping screen, assign each bank account to a YNAB account. You can map up to 4 bank accounts per institution connection. Extra bank connections each get their own mapping allowance. One connection = one institution login.
5. Sync runs on your schedule after mapping. Transactions sync automatically on your chosen schedule (default twice per day; you can add or change sync times on the connections page). Exact local times are shown for your timezone. You can also start a manual sync anytime from BudgetSyncer. With Enable Banking there is no separate daily limit on user-triggered syncs (banks may still delay publishing transactions).
