Sign in with Rainbow

This shows the first screen you are presented with after launching the Rainbow app!
In this guide, you will learn how to install Rainbow wallet on a mobile device, and how to import a seed phrase from another wallet like MetaMask.
Installing Rainbow
To get started, install the Rainbow app on your Android or iOS Device. Search for "Rainbow wallet" and then click on Rainbow - Ethereum Wallet on the Play or App store, then install and launch the app with the Open button.
This shows what the Rainbow app looks like on the App Store.
You will be greeted with two options:
Get a new wallet: Selecting this option instantly creates a new Rainbow wallet.
I already have one: Import another wallet.
Using a new wallet
Select the Get a new wallet option on the Rainbow app. After selecting this, you will see a screen that asks you to add some ETH. We will be skipping this, as MintKudos is on the Polygon network. You can proceed to the Signing in with Rainbow section below.
This screen shows after a wallet is created or imported on the Rainbow app. 
Importing another wallet
Select the I already have one option on the Rainbow app. You can use this feature to import another wallet using your secret phrase, private key, Ethereum address, or ENS name. For this tutorial, you will learn how to export a private key from MetaMask and import it into Rainbow.
This is the screen that shows when you try to import a wallet. Simply paste in your seed phrase to add it to Rainbow wallet!
Export Seed Phrase from MetaMask
This shows the MetaMask account screen on the MetaMask app. Tapping the hamburger menu in the upper left will open additional options and settings.
Open the MetaMask app and tap on the hamburger icon menu in the upper left. Tap on the Settings menu to open the settings for the app.
This shows the MetaMask app's side menu. You can tap on "Settings" to access options like the ability to export your secret recovery phrase.
Tap the Security and Privacy tab to access your Secret Recovery Phrase. 
This shows the available settings for your MetaMask account.
Once you are on the Security screen, tap the Reveal Secret Recovery Phrase button. You will be redirected to a screen that asks you to enter your password to continue. 
This shows the MetaMask app's Security & Privacy page. Clicking "Reveal Secret Recovery Phrase" will allow you to export your phrase so that it can be imported into Rainbow.
Read the warning on the screen and, if you are in a secure location, enter your password and click the Next button to reveal your phrase. 
You will see a popup that warns you to keep your SRP (secret recovery phrase) safe. Press and hold down the Hold to reveal SRP button to reveal your seed phrase. 
You can write down the displayed seed phrase or press the Copy to clipboard button for easy copying/pasting into Rainbow later. Note that if you use this feature, it will only keep the phrase copied for 1 minute.
Import Seed Phrase into Rainbow
After exporting your Seed Phrase from MetaMask, launch the Rainbow app. If this is your first time launching the app, select the I already have one option to begin importing your wallet. If you already have the app installed and already have a wallet, you can click on the arrow next to the wallet address to open a menu. Tap the Add an existing wallet button.
This shows the launch screen of the Rainbow app after it has been installed.
Enter your secret recovery phrase in manually or, you can press the Paste button to paste the phrase you copied in the previous step. Tap the Import button to proceed. Set a name for your wallet and then tap the Import Wallet button to import your wallet.
This screen shows that you can paste your Secret Recovery Phrase to import your wallet into Rainbow.
You may see a prompt asking If you'd like to back up your wallet to iCloud or another service. Choose whichever option you'd like. For the purpose of this tutorial, I opted to press No thanks.
