Cleanest banking solution.

Are there ideal options for secure ATM withdrawals. What are some of the optimal flow routing options ppl have mastered ? Would like to learn the best practice tricks.

I keep a separate bank account just to have reimbursements from benefits added in. No pay checks, no CRA deposits...etc I also keep a separate e-mail address associated with said bank account that is distinct from the email address I use for all my other accounts. It's also the email address I have for my burner phone.
