Firewall account question

[SkyCommander]

I'm doing a review of my finance accounts and wondering if I did this right and safe. Under one login I have 2 Capital One 360 Checking accounts. I have one 360 checking account tied only to PayPal with a very little balance in it that is my firewall account. My second 360 checking account I keep "a lot" in and it's used as my backup and travel debit card. Both accounts aren't linked to any banks and the only way to transfer money is push/pulls from my Chase checking. Those push/pulls can only go to my non PayPal linked 360 account then I can transfer it to my PayPal linked 360 checking account. Good set up? Flaws? Concerns?

I would make sure that the pay-pal checking account has the overdraft flag set to decline.

I believe C1-360 has about 4 overdraft options and you want your account locked down.

As easy as free checking accounts are able to be had.

I would add an additional layer of isolation by having the checking at another institution.

An account that has no other purpose than your pay-pal use.

So I could create an Ally account since I have no accounts or connections with them and use that one for my PayPal only? Then dump my second Capital One account?

I use my primary checking account as my firewall account and keep things simpler. Anything external links to checking (credit cards, autopay, etc) and then I use savings accounts to hold any cash that's going to be sitting around more than a week. It's easier for me because I have only one checking account so I know where everything links to. The one exception to this is brokerage accounts - those link to savings since I'm usually moving thousands or tens of thousands at a time.

One way to think of my model is going from short-term/many transactions to long-term/few transactions:

CCs/Autopay/DD --> Checking Account <--> Savings Accounts <--> Brokerages

The brokerages are also the most secure (MFA, randomized passwords that rotate every 60-90 days, no external links except to savings) so it makes sense that they hold most of my wealth.
