If your Mail.ru inbox suddenly stopped updating in the Mail app on your iPhone or Mac — showing sync errors or asking for your password again and again — you are not alone. Mail.ru tightened its security standards, and third-party mail clients now need a special app-specific password instead of your regular account password. The fix takes just a few minutes, and you have three good options depending on how you like to read your mail.
Why Mail.ru stopped working in Apple Mail
Mail.ru introduced stricter data-protection standards for everyone connecting through third-party apps. Your regular account password no longer works in Apple Mail or other external clients — the server rejects it, which is why you see endless password prompts or sync errors. This affects the Mail app on iPhone, iPad, and Mac alike. Mail.ru is not the only provider to do this; if you have ever struggled with adding a Yandex mailbox in the iPhone Mail app, you have seen the same pattern: providers now want each app to use its own limited password. The solution is to generate one.
How to get Mail.ru working again
Pick the method that suits you best. Method 2 keeps your beloved Apple Mail working and is what most people choose.
Method 1 — Use the official Mail.ru app
If you do not mind switching apps, install the official Mail.ru client from the App Store, sign in with your regular credentials, and your mail will work immediately — no extra passwords needed.
Method 2 — Create an app-specific password
- Open Mail.ru webmail in any browser and sign in to your account.
- Go to Password and security > Security > Passwords for external apps.
- You will need a verified phone number and two-factor authentication turned on — Mail.ru will prompt you to add them if they are missing.
- Generate a separate password for each app: one for Mail on iPhone, one for Mail on Mac. Each code only works for the app it was created for.
- In Apple Mail, update the account with the generated code instead of your regular password, and your inbox will start syncing again.
Method 3 — Collect or forward your mail elsewhere
If you would rather not juggle extra passwords, set up automatic mail collection in another service or forward everything to iCloud. You can pull Mail.ru messages into a different inbox automatically, or create a forwarding rule in Mail.ru settings so copies land in your iCloud mailbox — handy if you already use your hidden iCloud email address for sign-ups.
If it still doesn’t work
Double-check that two-factor authentication is actually enabled — codes cannot be created without it. Generate a fresh code for each device rather than reusing one, and make sure IMAP access is allowed on your account. Apple Support has in-depth troubleshooting for mail connection errors, and tech press like TechCrunch has covered why providers keep tightening these rules. Visual setup walkthroughs on YouTube can also guide you through the clicks.
Frequently asked questions
Is an app-specific password safe?
Yes — arguably safer than the alternative. Each code works only in one app and can be revoked individually without changing your main password.
Will this break webmail access?
No. Browser access keeps using your regular password; only external apps need the special codes.
Conclusion
Mail.ru did not break your mail — it just raised the bar for third-party access. Generate an app-specific password for each mail app, or switch to the official client, and your inbox will be flowing again in minutes.
