+## Seed Actions
+
+Long-pressing a card opens a menu with:
+
+### Export seed
+
+A dialog titled `{bank} · {name}` showing:
+- A QR code of a minimal `otpauth://totp/{BANK}?secret=…` link (e.g. `otpauth://totp/BML?secret=…`), always drawn black-on-white so it scans in dark mode. No username or issuer is included, and algorithm, digits and period are left out because SHA1, 6 and 30s are the spec defaults. Export is single-account only; `otpauth-migration://` is supported for import but never produced.
+- The Base32 seed in groups of 4 (selectable text)
+- A **Copy seed** button. The copy is flagged `EXTRA_IS_SENSITIVE`, so Android 13+ hides the value in the clipboard preview.
+
+### Update seed
+
+Replaces the stored seed for that login, e.g. after re-enrolling the authenticator with the bank.
+- A red warning banner explains that the old seed is deleted permanently.
+- The new seed can be typed or pasted (raw Base32 or an `otpauth://` link) or scanned with the QR button. Scans that contain several accounts (`otpauth-migration://`) ask which one to use.
+- Once the input is a valid seed, a live preview shows its current and next code with a countdown so the user can check it against the bank before saving. The preview is the same card as the sign-in screen (`view_otp_preview.xml`, shared by both), and tapping it copies the code. Input that isn't valid Base32, is shorter than 8 characters (such as a pasted 6-digit code), or matches the current seed disables **Replace**.
+- **Replace** asks for confirmation ("Delete old seed?"). Confirming calls `CredentialStore.updateMibOtpSeed()` / `updateBmlOtpSeed()`, which overwrite only the encrypted seed. For MIB it also calls `MibLoginFlow.updateOtpSeed()` so silent re-login uses the new seed.
+
+The username, password and sessions are not touched. Other places that need an OTP (transfers, QR pay, pay with card) read the seed from `CredentialStore` each time, so they pick up the new seed immediately.

+Reset your Bank of Maldives authenticator to get a new OTP seed, then add that seed to Thijooree so it can generate your OTP codes.
+
+> [!NOTE]
+> You need the BML app signed in, and a BML debit card with its expiry date and CVC to confirm who you are.
+
+> [!IMPORTANT]
+> Want the same codes in another authenticator app too, such as Microsoft Authenticator or Google Authenticator? Add the secret key to that app **after step 5 and before step 7**. After you tap **Verify Code**, BML stops showing the secret key and you would have to reset again. See [Export from Microsoft Authenticator](04-export-microsoft.md) for the steps.

+# Set up MIB
+
+Maldives Islamic Bank doesn't let you reset your authenticator from the app. The only way to get a new OTP seed is to ask customer care, and then wait. And wait some more.
+
+> [!NOTE]
+> You need patience, a working email address and a small amount of faith. Results may vary.
+
+## How to do it
+
+1. **Contact customer care**<br>
+   Get in touch with MIB customer care and ask them to reset your authenticator and send you a new secret key.
+
+2. **Perform the summoning ritual**<br>
+   Light a candle, face the direction of the nearest MIB branch and chant *"please reply, please reply"* three times. Offering a cup of tea to the ticket gods is optional but recommended.
+
+3. **Wait for the email**<br>
+   MIB emails you the new secret key. Eventually. Check your inbox, then check your spam folder, then check your inbox again.
+
+4. **Wait more**<br>
+   Still nothing? This is normal. Refresh your inbox. Touch grass. Refresh your inbox again.
+
+5. **Perform another ritual**<br>
+   Repeat step 2, but with two candles this time. If it has been a few working days, a polite follow-up to customer care also works, and is less of a fire hazard.
+
+6. **Add the seed to Thijooree**<br>
+   Once the email arrives, copy the secret key from it. Open Thijooree, go to the **faisanet** sign-in screen and paste the key into **OTP Seed (TOTP Secret)**. The **Current OTP** appears below it.
+
+## Log in to Thijooree
+
+Once the key is in, in Thijooree:
+
+1. Enter your MIB **Username** and **Password**.
+2. Tap **Login**.
+
+> [!TIP]
+> Already have your MIB account in Google Authenticator or Bitwarden? Skip the rituals entirely and see [Export from Google Authenticator](03-export-googleauthenticator.md) or [Export from Bitwarden](05-export-bitwarden.md).
+
+> [!WARNING]
+> The secret key gives full access to your OTP codes. Don't share it, and delete the email once you have logged in.

+# Export from Microsoft Authenticator
+
+Microsoft Authenticator can't export TOTP seeds unless your phone is rooted, so you can't move an existing seed out of it.

+# TOTP Seed
+
+## What is a TOTP seed?
+
+A TOTP (Time-based One-Time Password) seed is the secret key your bank gives you when you set up its authenticator. It looks like a string of capital letters and numbers such as `JBSWY3DPEHPK3PXP`, or comes inside a QR code as an `otpauth://` link.
+
+## Thijooree needs the seed to: 
+- Enable OTP-less Transactions.
+- Show your OTP codes (to use official bank app or website along with Thijooree.)
+
+To keep transactions secure, you can have Thijooree ask for your biometrics instead of an OTP. \
+Keep your seed private: anyone who has it can make your OTP codes.
+
+## How do I get my TOTP seed?
+
+You get your seed in one of two ways:
+
+### Setup
+
+1. [Set up BML](01-setup-bml.md)
+2. [Set up MIB](02-setup-mib.md)
+
+### Export
+
+3. [Export from Google Authenticator](03-export-googleauthenticator.md)
+4. [Export from Microsoft Authenticator](04-export-microsoft.md)
+5. [Export from Bitwarden](05-export-bitwarden.md)
