The UIDAI has launched their official android mobile app. The app enables the user to add their Aadhaar Number to the App and later use the app as the identity proof.

1. m-Aadhaar Mobile App byUIDAI
Government of India have used mobile phones to provide many
services to its citizens. The latest is the launch of m – Aadhaar app
which is launched by UIDAI (Unique Identification Authority of
India).
This app is very convenient and handy as it allows the subscribers to
carry their Aadhaar numbers which also works as an identity card in
their pocket.
The app will contain all the required information such as demographic
details, name, date of birth, gender, postal address and photograph,
after you link your Aadhaar with the app. And you can carry it
everywhere, all the time.
UIDAI also provides lock unlock system where if an individual wants
they can lock their biometric details on Aadhaar in order to protect
privacy and confidentiality of their biometric data.
“If you do not intend to use your biometrics in your near future, you
can lock you biometrics”
However, this facility was available only on the UIDAI official
website earlier https://uidai.gov.in/ .
Now m –Aadhaar is also offering the lock unlock biometric data
facility to people which will help them to prevent their biometric data
from potential misuse.
Another most useful feature of m – Aadhaar is it uses two – layer
authentication for safety and security purposes. First, the app allows a
user to update their profile using the app, and the change reflects in
the app once they are approved. It also uses Google Authenticator i.e.
OTP (One Time Password) generation tool.

2. In order to use m –Aadhaar app, the subscriber is required to
download the app and set a password, and enter your Aadhaar number
or you can scan your bar code which is on the Aadhaar card as well.
Once that is done, the app will send you a SMS which contains the
OTP, and the app will read the OTP automatically; as there is no way
to enter it manually which is also considered to be one of the
drawbacks of the m – Aadhaar app.
However, if you are facing crashing problem, as the app is not reading
the OTP automatically, read the below mentioned steps suggested by
UIDAI:
1. Go to the settings
2. Go to permissions control
3. Go to apps
4. Go to m Aadhaar app
5. Allow the read SMS option.
