Verify multilingual authentication messages

The multilingual phrases you provided all correctly convey "Authentication successful" in the given languages. Short verification:

• English: "Authentication successful" — correct.
• Hindi: "प्रमाणीकरण सफल" — correct phrasing; often also written "प्रमाणीकरण सफल है" to read as a full sentence.
• Chinese (Simplified): "身份验证成功" — correct.
• Japanese: "認証に成功しました" — correct and natural (polite past).
• Arabic: "تمت المصادقة بنجاح" — correct (literal: "authentication was completed successfully").
• Emoji: "😀 🚀 ❤️ 👍🏽 🌍" — expressive; emojis don't carry a precise authenticated-status meaning but can accompany a success message.

If you want these as exact UI strings or variants for different contexts (short label, full sentence, informal vs. formal), tell me the target language(s) and context and I can provide alternatives and locale-aware suggestions (including scripts, punctuation, and RTL handling for Arabic).
