Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A communication apparatus comprising:
one or more processors; and
one or more memories that store a computer-readable instruction for causing, when executed by the one or more processors, the communication apparatus to:
accept an input of an authentication scheme and a passphrase by a user operation;
determine whether or not a passphrase length of the inputted passphrase meets a condition of a passphrase length related to the inputted authentication scheme, wherein the passphrase length is the number of characters in the passphrase;
in a case where the passphrase length does not meet the condition, set an authentication scheme that supports the passphrase length, and perform wireless connection with a partner apparatus using the set authentication scheme; and
in a case where the passphrase length does not meet the condition and the passphrase length is within a predetermined range and no more than 63 characters, a user selected authentication scheme corresponding to an item selected by user operation from among a plurality of items containing at least WPA (Wi-Fi Protected Access), WPA2, WPA3, or a combination of at least two of WPA, WPA2, and WPA3 is set as the authentication scheme, and perform wireless connection with a partner apparatus using the set authentication scheme,
in a case where the passphrase length meets the condition, perform wireless connection with a partner apparatus using the inputted authentication scheme.
