FQL v4 will be decommissioned on June 30, 2025. Ensure that you complete your migration from FQL v4 to FQL v10 by that date.

Fauna accounts created after August 21, 2024 must use FQL v10. These accounts will not be able to run FQL v4 queries or access the v4 Dashboard.

For more details, see the v4 EOL announcement and migration guide. Contact support@fauna.com with any questions.

Description

The HasCurrentIdentity function returns true if the current client authentication credentials have an associated identity, and false if they don’t.

When authentication is performed by an identity provider, HasCurrentIdentity returns true if the associated JWT has a sub field.

Parameters

None.

Returns

A boolean indicating whether the current client credentials are associated with an identity/JWT.

Examples

The following query is run in the context of a logged-in Fauna user:

client.query(
  q.HasCurrentIdentity()
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
false
result = client.query(
  q.has_current_identity()
)
print(result)
False
result, err := client.Query(
	f.HasCurrentIdentity())

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
false
try
{
    Value result = await client.Query(
        HasCurrentIdentity()
    );

    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
BooleanV(False)
System.out.println(
    client.query(
        HasCurrentIdentity()
    ).get());
