when did you last used the stake? make sure did you log in using any mails that appeared to be sent via stake and also check whether your other wallets or keys are secure if not try changing it to some other system or drive for safety if every other thing are safe just make sure did you make a login to stake through links from external sites or using any free VPN services
Unfortunately what happened to him already happened and there is no way to bring it back but it could be used as a cautionary tale at least to other people who do not have 2FA or any other stuff.
We live in a world where you can have apps on your computer (offline apps with no internet connection) that you can store all of your passwords and generate strong ones and basically you can just open that app whenever you want to go online and all your different usernames that is unique for each website and all of your unique passwords to each website will be on that app so you have no chance of forgetting it, they even store your old ones as well and new ones so that if you forget which one it was you have ALL the passwords you used for that website. It helps you both have awesome passwords that are hard to crack and unique to all websites you use so you get thousands of different passwords but it also helps you remember them all as well.
That's right having the same password for all or most of the platforms is always very risky having that password manager is one of the best possible options available right now so do you suggest any of the best such apps? or the ones do you use just might help others to save some time in searching for those or filtering some
