Unlike your bank, there are very limited password recovery options with Bitcoin. In fact, you should be able to remember your password even after many years without using it.

An offline wallet, also known as cold storage, provides the highest level of security for savings. It involves storing a wallet in a secured place that is not connected to the network.
When done properly, it can offer a very good protection against computer vulnerabilities. Using an offline wallet in conjunction with backups and encryption is also a good practice. Here is an overview of some approaches. This approach involves having two computers sharing some parts of the same wallet. The first one must be disconnected from any network.

The second computer is connected to the network and only has a watching wallet that can only create unsigned transactions.
