Is JWT authorization implemented securely?

Question

JSON Web Token

Good afternoon. Straight to the point.
Implemented authorization using jwt.
The user logs in to the site, the generated token is returned to him through the api.
The token is written to localStorage as key:value
On subsequent actions of the user, the token is checked, if everything is OK, then the user receives the requested data.
Is everything implemented correctly and is it safe?

Answer 1

Yes, everything is quite safe.
