If your Binance API expired, and you want to keep the same Binance institution in Wealthica, to prevent losing the history, you should create a new API in your Binance account.

After that, you should log in to your Wealthica account, expand the Binance institution, then click "Edit" and on the edit window click on "Edit Credentials"

This should allow you to re-authenticate for your existing Binance connection, and not lose any data!
