I usually spend some time with Discord’s DM to say what I am doing.
In recent years, it seems that many people forget their wallet passwords recently.
If you forget, coins will be lost.
Even management cannot move coins for which the password has been forgotten.
By the way, this password is for wallet.dat itself. Therefore, even if you back up after setting the password, and then set “another password”, the previously backed up wallet.dat is “leave the previous password”. Using this property, if you keep them with different passwords, at the worst, if you remember at least one, all coins there will be OK.
Be careful with password management.
