Your phone’s texts and codes, on your desktop.

Resano sends the texts and verification codes your Android phone receives to your computer, fills codes in your browser, and lets you answer from the keyboard you are already using. Your phone sends the reply. Nobody in between can read any of it.

How it works

Set it up once. Then forget it’s there.

01
Install on your Android phone
Resano listens for incoming SMS in the background, even when the app is closed. Choose all messages, codes only, or just the senders you pick.
02
Link your desktop
Open Resano on your computer and scan its QR code with your phone. Both screens show the same number, and you approve it on the desktop.
03
Codes arrive, replies go out
New messages appear on your desktop within seconds. The browser extension offers a code under the field and fills it when you press Enter. To answer a message, type the reply on your computer and your phone sends it.

What you get

Small, quiet and exact.

End-to-end encrypted

Messages are encrypted on your phone with AES-256-GCM and decrypted only on your devices. The relay passes along ciphertext it cannot read.

No account, just a vault

Your devices share a vault instead of a login. Twelve words, shown once, let you add or recover a device. No email, no password, no phone number.

Fills codes in your browser

The extension finds the code field, offers the newest code and fills it, single box or split boxes. It never submits a form for you. Each browser profile chooses which of your phones may offer it codes.

Every desktop you use

Link a Mac at work and a Linux box at home to the same phone, or two phones to one vault. Each device gets its own permissions, and you can remove any device from any other. Conversations are grouped per phone and SIM.

Reads Persian codes

Persian and Arabic digits are normalised, and amounts or card numbers are never mistaken for codes. When it isn’t sure, it asks.

Discreet by default

Desktop notifications show only how many messages arrived, never who sent them or what they say. Old messages can delete themselves.

Reply from any of your devices

Type a reply on your computer and your phone sends it as a normal text, from the SIM the message arrived on. You see it as sent and delivered. Replies go to numbers that texted you, up to 60 an hour, and stay off for a new device until you allow them. Optional Instant replies keep the phone listening so a reply goes out in seconds; without it, up to about 15 minutes.

Names and photos, only if you want

Turn on Contacts on your phone to see names and photos instead of numbers, and to search your phone’s contacts from your computer when you start a conversation. They are looked up on your phone and travel encrypted between your devices. Your address book is never uploaded or kept on our server.

Made for the desktop

Keyboard shortcuts and menus for everything: new message, search, jump to a conversation, reply, lock. Starting a conversation with a new number is a separate switch, off by default, with a limit of 20 new numbers a day.

Security

The relay sees noise.

To reach your desktop when you are not on the same network, Resano passes messages through a relay at api.resano.app. It only ever holds encrypted envelopes, keeps them briefly, and forgets them once your devices confirm delivery.

Keys are created on your devices and kept in the Android Keystore and your desktop’s secure storage.
Each device is approved by you, on a screen you can see, with a matching number.
Removing a device stops it from receiving new messages straight away.
Codes are filled only into the tab you are looking at, and only codes from the last ten minutes.
Replies are sent by your phone only when you have switched them on and the asking device is allowed to reply. The phone checks every request, answers only numbers that texted it, and caps how many it sends.
Contacts stay on your phone. If you switch them on, names and photos reach your other devices only inside the encrypted messages.

Resano is still in development. An independent security review is planned before the first public release.

Platforms

Android may say it hasn’t seen this developer before. That is normal for a new app: tap “Install anyway”.

iPhone can’t share incoming SMS with other apps, so Resano needs an Android phone to receive codes.

FAQ

Questions

Can Resano read my messages?

Only your own devices can. Messages are encrypted on the phone before they leave it, and the relay never has the keys.

Do I need to create an account?

No. Your devices form a vault protected by twelve words. Keep them somewhere safe: they are the only way to recover the vault if you lose every device.

Does it work with an iPhone?

Not for receiving codes. iOS doesn’t let apps read incoming SMS. The desktop app and extension work with an Android phone.

Will it submit forms or log in for me?

No. Resano fills the code and stops. You stay the one who presses the button.

Which messages are sent to my desktop?

You choose on the phone: every SMS, only messages with a code, or only the senders you pick. Filtered messages never leave the phone.

Can I reply to a message from my computer?

Yes. You type the reply on your computer and your phone sends it as a normal text message, so your carrier’s usual SMS charges apply. Replies go to people who have texted that phone, up to 60 an hour. A new device can’t reply until you allow it, and with Resano closed on the phone a reply can take up to about 15 minutes, or seconds with Instant replies switched on.

Can I start a new conversation?

Only if you switch on Start conversations on your phone and allow it for that device. It is off by default, one recipient at a time, and limited to 20 new numbers a day. Resano never sends in bulk.

Does Resano see my contacts?

No. With Contacts switched on, your phone looks up the names and photos of the people you text and shares them with your own devices, encrypted. It is off by default. Your address book is never uploaded, and the relay only passes along encrypted envelopes.

Will my replies show up in my phone’s messages app?

No. Resano is not your phone’s default messaging app, so replies are not written into it. They appear in Resano’s own conversation on every one of your devices.

How much does it cost?

Resano is free while it is in beta. Pricing after that hasn’t been decided.

Stop reaching for your phone.

Resano is free during the beta. Install it on your Android phone, then on your desktop and in your browser.
