Android . password manger


I already wrote like 50 lines but something happen and i have to start over. I just want to know how to make the password manager work for android? I have tried both Brave and Chrome browsers but in there settings its only "turn password manager on or off".. i can not set another app as password manager.. So i bought it to have it on my phone.. computer as well but phone was most important!

So do i have to use a supported browser or wait for updates? Please help me because people are trying hard to pish me and stuff so i really need the random password generator and the manager to work and i needed it yesteray :(

The app seems like its very well made and stuff so i bet i am the error! So lay it on me, what did i do wrong?

Thanks in advance for any help/information regarding this issue
