What app is recommended to store usernames and passwords (i have to many usernames and passwords, i’m having hard time to remembering those)?

I can recommend Keepass and Bitwarden.

I used to use Keepass and I am currently using Bitwarden.

  • Keepass if you want your password vault offline and use your own method of syncing between devices. Its more manual than bitwarden.
  • Bitwarden comes with a cloud syc. You can either use the official bitwarden cloud service or host your own bitwarden instance.

I am using the free tier of Bitwarden so far I had no need for the paid features.
