Problem while accessing resources

[shreyabaid007]

Request- curl -H "Authorization: Bearer 1234567890" localhost:8081/account
Response- {"error":"invalid_token","error_description":"Invalid access token: 1234567890"}

But the endpoint that gets access token works fine for me, i.e., localhost:8081/oauth/token?client_secret=secret5&client_id=web5&grant_type=password&username=XYZ&password=1234

What am I doing wrong here?
