If you do not have your backup phrase:
If you do not have your backup phrase, then, unfortunately, you have lost your wallet and all funds in the wallet. For security, 12 word backup phrases are not stored on BitPay servers, so BitPay cannot recover funds for you.
If you still have your backup phrase:
Open the app and go to the gear icon at the bottom right. Then scroll down and choose Create or Import a Key. Then, choose Import Wallet and the Recovery Phrase tab. Type out your 12 word recovery phrase and click Import to restore your funds. Do not use any punctuation.
If you have a file or text backup:
Open the app and go to Settings (the gear icon) at the bottom-right. Then scroll down and choose Create or Import a Key. Next, choose Import Wallet and the File/Text tab.
* File format: from Windows, Linux, and Mac. Upload the file.
* Text format: from mobile devices. Paste the json format as plain-text.
Note: All File/Text backups have a password. You will need to enter this password in order to restore your wallet.
I want to access my wallets on all my devices, what can I do?
To be able to use the BitPay app in all your devices simply install the BitPay app on each of the devices and import the Key/s (see If you still have your backup phrase above in this article).
Please make sure all your devices are properly secured. If someone has access to a device, they may access your wallets and funds.
To add an encrypt password to a key, open the app and go to Settings (the gear icon) at the bottom-right. Then scroll down and choose the key you want to secure. Next, enable Request Encrypt Password. Enter the password and confirm it.
