Frequently Asked Questions

Why does Plaid keep saying my bank password is wrong when it works on the bank's website?
This often happens when your bank has additional security measures for third-party connections that differ from direct website access. Your bank may require you to enable API access or approve Plaid specifically through their security settings.
How long should I wait before trying to reconnect after getting INVALID_CREDENTIALS?
Wait at least 15-30 minutes between connection attempts to avoid triggering additional security lockouts. Too many rapid attempts can cause your bank to temporarily block third-party access entirely.
Can I use Plaid if my bank requires two-factor authentication?
Most banks that support Plaid have configured their systems to work with two-factor authentication, but the process may require additional steps. Some banks may temporarily disable 2FA for API connections or handle it automatically during the linking process.
What should I do if my bank isn't supported by Plaid?
If your bank doesn't appear in Plaid's supported institution list, you'll need to either switch to a supported bank or use manual account linking methods if the financial app offers them. Plaid continuously adds new banks, so check back periodically.
Is it safe to enter my banking credentials through Plaid?
Plaid is a legitimate financial technology company used by major apps like Venmo, Robinhood, and Mint. They use bank-level security and encryption. However, always verify you're on the official app and never enter credentials on suspicious or unverified websites.
