What password manager/ generators do you suggest?

Also would anyone please clear my possibly misconceptions on the password manager/generators?

I’m that type of guy that only uses few password combinations at different websites.

tl;dr: my account out leaked, I didn’t want to use any password manager because I don’t want to give password to the company. Some do generate complex password for me but if they become defunct I’ll be locked out from those accounts.

A while ago, aptoide got attacked and my password(same as google account) was leaked. I’ll have to thank google for this, google blocking a stranger accessing account using a “less secure app” So now I’ll doing a emergency password changing process to all of my accounts with the password.

I like the whole aspect of the password manager, but I always thought that I shouldn’t give my password to other companies. And I got to use some website long term, if the password management company ever just become defunct, I might lose access to my account forever.
