The beta version of blue mobile does not permanently retain passwords per account. In order to keep the password for reuse the user needs to setup an iCloud Keychain account and input the password there.
How do I enable iCloud Keychain?
Sourcing From: Apple Support
Once iCloud Keychain is enabled it will keep your Blue Mobile login information across all apple devices (iPhone, iPad, etc..)
Once iCloud Keychain is enabled it will automatically capture your passwords and save them to your apple device.
If you want to add passwords manually vs. automatically you can also do that.
Here is how:
- Click the Settings App on your iPhone
- Scroll down and tap Passwords
- Enter you passcode
- Tap the plus icon which is allocated in the top right corner of your screen
- Enter the website, username and password for Blue Mobile
- Click Done at the top right to save your work
