The best thing is to make sure to setup 2FA on all your accounts be it text messaging or an app and have your mobile number set correctly on your banking account so that they can alert you. If you have an app, then use face id lock recognition on your phone and using the feature to "hide the app" on the phone too.
Also (
this is what i do on top ) I have a dedicated laptop for banking only, that is encrypted with bit locker, and another encryption software to store my passwords in an encrypted file on it - so there are two layers of encryption to get through through and those passwords i have never written down anywhere ever. I make backups to another portable drive that is also bit locker encrypted with the password file copied onto it in case the laptop dies( and I have copies at 2 different locations!). The worst think you can do is write down your passwords on paper!
That laptop It only has antivirus on it and chrome and "nothing else at all" and
I ONLY EVER USE IT access my banks and investments on it. I never visit any other site on it ever. Ever. Ever.
Also, the email address i use for "main" banking apps, i never use anywhere else for anything, so there is no risk of leakage of that email address. I create one for banking, and another different one for your bills, websites, amazon etc ... Obfuscation is part of the plan to protect yourself. That also means, social engineering is more difficult as they won't be able to get some of your core credentials. And of course, don't share your information on social media etc.
I even have a separate "burner bank account" for bills and everything else and my private one for the large cash flows is get restricted on who knows its details etc.
Here in the UK, the safest place to put your money is
https://www.nsandi.com/ if you are worried about your bank going down(though savings are protected at each bank up to £120,000 per financial institution).
I also have an identity protection service that i paid for, which alerts me straight away if my details have become compromised in any way, or if people try to do anything with my credit record or try and take out a loan in my name etc...
And - yes - I have that crazy setup.
