The only big danger of a good password manager is the fact all your passwords are stored under one.
To mitigate the risk, follow these practices:
Use a good trusted, much preferably open-source option (for example, Vaultwarden, KeePassXC);
Use a strong password;
Do not EVER use the same password you use for password manager elsewhere;
Use 2FA on both your password manager itself and all the accounts you store passwords for;
Backup your password database in an encrypted way.
Together, these measures should save you from any trouble.
Now, why they are good:
They can generate and store very strong passwords you would never make up, much less remember;
You can be sure you won’t forget your password;
They are convenient and can auto-fill passwords for you.
Generally, using a password manager is considered a superior option in terms of security and availability compared to keeping your password elsewhere, including your head.
