This is a really big problem for those who forget their bitcoin wallet passwords. You know that your tokens are lying there but you can't gain acess to it.My only suggestion is to write down your password and save it someplace else, only for your personal use.
Security and keeping safe your private keys is a must because once it will lose it is really hard to retrieve the access to your bitcoin wallet. I'm not sure if others can retrieve it with the links above of op, so delicates to try it. It is very important not to lose any single details of our bitcoin wallet.
