I want to login with username,email id and phone number in wordpress

you can use this plugin to login and register with phone number or email and password. the code will be send to you with sms or email and you can authenticate with that. and your customer can set password for him/her , so it does not need to send activation code via sms or email again.

Assuming you store the phone number in user_phone meta field. You can use the below code that I use in one of my plugins "Actions Pack" which provides user registration and login facility for Elementor page builder.

// Login through phone number
add_filter( 'authenticate', function ( $user, $phone, $password ){
    if ( $user instanceof WP_User ) {
        return $user;
    }

    if ( empty( $phone ) || empty( $password ) ) {
        if ( is_wp_error( $user ) ) {
            return $user;
        }

        $error = new WP_Error();

        if ( empty( $phone ) ) {
            // Uses 'empty_username' for back-compat with wp_signon().
            $error->add( 'empty_username', __( '<strong>Error</strong>: The phone field is empty.', 'actions-pack' ) );
        }

        if ( empty( $password ) ) {
            $error->add( 'empty_password', __( '<strong>Error</strong>: The password field is empty.', 'actions-pack' ) );
        }

        return $error;
    }

    if ( ! ap_is_phone( $phone ) ) {
        return $user;
    }

    $user = get_users( [ 'meta_key' => 'user_phone', 'meta_value' => $phone, 'number' => 1, 'count_total' => false ] )[0];

    if ( ! $user ) {
        return new WP_Error(
            'invalid_phone',
            __( 'Unknown phone number. Check again or try your username.', 'actions-pack' )
        );
    }

    /** This filter is documented in wp-includes/user.php */
    $user = apply_filters( 'wp_authenticate_user', $user, $password );


    if ( is_wp_error( $user ) ) {
        return $user;
    }

    if ( ! wp_check_password( $password, $user->user_pass, $user->ID ) ) {
        return new WP_Error(
            'incorrect_password',
            sprintf(
            /* translators: %s: Phone Number. */
                __( '<strong>Error</strong>: The password you entered for the phone number %s is incorrect.', 'actions-pack' ),
                '<strong>' . $phone . '</strong>'
            ) .
            ' <a href="' . wp_lostpassword_url() . '">' .
            __( 'Lost your password?' ) .
            '</a>'
        );
    }

    return $user;
}, 20, 3 );

Here is a phone number validity check function. It depends on how you receive your phone number. Is it with country calling code or not.

/**
 * Checks if it is a valid phone number
 * @toDo Improvise validity check.

 */
function ap_is_phone( $phone ){

    $phone = filter_var($phone, FILTER_SANITIZE_NUMBER_INT);
    $phone = str_replace("-", "", $phone);

    if (strlen($phone) < 10 || strlen($phone) > 14) {
        return false;
    }

    return $phone;
}
