It's encouraging to see Plaid making this level of effort to be accurate. It seems like it could be a viable alternative to Mint using something like <a href="https://github.com/yyx990803/build-your-own-mint" rel="nofollow">https://github.com/yyx990803/build-your-own-mint</a> (written by the author of Vue.js).<p>It's scary to think what would happen if one of these services (Mint, Personal Capital, Plaid) had a backend data breach. If they can log in to your financial sites, a breach would mean the attacker would be able to as well.
